backups: monitor both the dump and the pull, per source
Twelve endpoints in two groups, because they answer different questions and
fail for different reasons:

  backup-dump_<svc>       pushed by the SOURCE right after its dump runs
  backup-store_<svc>      pushed by the BOX at 05:30, per source
  backup-store_pull-job   pushed by the BOX, about the box itself

The store alone could catch almost everything, because the artefact filename
carries the source's dump timestamp - a source whose timer died still pulls
"ok" forever, but the timestamp gives it away. What the source side adds is
LATENCY and DIAGNOSIS: the store only learns at the next 04:00 pull, and it
cannot tell you whether the dump broke or the pull did.

pull-job is separate from the per-source checks because it is a LEADING
indicator where those are lagging ones. A disabled pull timer, a failed pull
job, or a filling disk are all visible immediately, while the per-source checks
only fire once an artefact is >26h stale - about a day later. Disable the timer
at 10:00 and every source stays green until tomorrow; pull-job goes red this
morning and names the cause instead of showing six stale sources.

Frequencies: dumps 02:00-02:30 staggered, pull 04:00, verification 05:30, all
daily and Persistent. 26h staleness decides red; a 30h Gatus heartbeat catches
the verification itself having stopped, so a dead check-backups.timer cannot
hide a stale backup.

arbret has no dump endpoint: prd-arbret is in [arbret], which `managed`
deliberately excludes, so nothing of ours runs there. Store-checked only.

check-backups.sh was manual-only; it now runs on a timer and reports per source
rather than only printing. The human-readable report is unchanged.

A SERIOUS bug introduced and fixed in this change, recorded because the shape
is easy to repeat: the reporting hook was added to backup.sh as a second
`trap ... EXIT`. Bash REPLACES the EXIT handler rather than adding to it, so
that silently deleted the trap which restarts the stopped service - the one the
script's own comment calls "the point", and the bug the role was written to
eliminate. Every backup then stopped its service and left it stopped. It took
forgejo, lnbits, headscale and memos down for several minutes each, and nothing
caught it: the dumps exit 0, the artefacts are correct, the deploy reports
failed=0, and liveness only proves the HOST is up. There is now ONE EXIT
handler doing both jobs, armed BEFORE the stop so a failure during the stop
still restarts. Verified by rendering both variants, asserting exactly one EXIT
trap in each, and simulating a mid-way failure to confirm the restart fires.

Verified: all 12 endpoints UP; six sources pulled cleanly (arbret 31M,
headscale 198K, memos 7.8M, vaultwarden 2.1M, lnbits 30M, forgejo 2.6G), store
16% full, "RESULT: all checks passed".

Known gaps, deliberately not closed here:
  * `yell` warnings - disk 75-90%, an artefact under half the previous size,
    retention not pruning - never reach Gatus, because a push is binary.
  * Nothing verifies a backed-up service came back UP. That is the gap that let
    the trap bug run unnoticed, and it is what the next change addresses.

ansible: move the cross-host ports to host_vars, delete services_config.yml
The four ports were the only entries in services_config.yml with a real
justification: each is read twice, by the role that deploys the service on its
own box AND by a socket-proxy or Caddy play that runs on the EDGE host and
publishes it. A role default is invisible to that second play.

But the shape was wrong in two ways. The file had to be named in vars_files: by
30 plays - opt-in configuration that someone will eventually forget - and five
role defaults silently interpolated service_settings.*, so bitcoin_knots,
fulcrum, datum_gateway and mempool were not self-contained: using any of them
without that one vars_file entry broke it.

Each port now lives in host_vars/<owning box>/main.yml:

  host_vars/knots_box_local/main.yml    bitcoin_p2p_port, datum_gateway_api_port,
                                        datum_gateway_stratum_port
  host_vars/fulcrum_box_local/main.yml  fulcrum_ssl_port
  host_vars/mempool_box_local/main.yml  mempool_frontend_port

host_vars auto-loads and outranks role defaults, so the owning role picks the
value up with no vars_files at all, and the edge play reads the same single
definition as hostvars['<host>'].<name>. The role defaults keep the protocol
standard (8333, 50002, ...) so each role still works standalone, with the live
deployment's value in host_vars winning.

Also fixed a fourth copy of an inventory identity: the mempool Caddy play had
"mempool-box:{{ ... }}" hardcoded in the upstream. It now derives the host from
hostvars['mempool_box_local'].ansible_host, so inventory is the only place any
box's name is written down.

services_config.yml is deleted, with 25 more vars_files entries across 19
playbooks. Between this and the previous commit, 87 vars_files entries are gone
and every variable in the repo now comes from group_vars/all, host_vars,
inventory, a role default, or that service's own *_vars.yml.

Verification: an edge-host probe resolves all eight ports and hostnames to
byte-identical values to the ones services_config.yml used to supply. Each
owning host resolves its own port through host_vars. All 37 playbooks'
--list-tasks output is unchanged. The four edge plays that consume these values
all check-diff changed=0 - the socket-proxy and Caddy units on vipy are
byte-identical, which is the direct proof the rewiring landed on the same
values. fulcrum and datum-gateway check-diff exactly as before (ok=28/changed=1
and ok=15/changed=1, both the known timer re-arm).

ansible: delete the duplicated vars files, move globals to group_vars/all
Three files existed only as second copies of things group_vars/all already
auto-loads, and 34 playbooks named them in vars_files: - which outranks
group_vars, so the copies won. The day someone edited one and not the other,
those plays would silently keep the stale value. infra_vars.yml was already
drifting: group_vars/all/main.yml had grown age_backup_recipient and
backup_pull_public_key that it lacked.

  infra_vars.yml          - a strict subset of group_vars/all/main.yml
  infra_secrets.yml       - decrypts byte-identical to group_vars/all/vault.yml
  infra_secrets.yml.example - documented Uptime Kuma credentials as the reason
                              the file exists, which stopped being true

Deleted, along with 62 vars_files entries across 34 playbooks (12 of which
named ../../group_vars/all/main.yml directly - same defect, a vars_files entry
duplicating an auto-loaded file at higher precedence than the file itself).

Checked before touching anything: infra_secrets.yml was listed LAST in 10 plays,
after services_config.yml, so removal would flip precedence if the two shared a
key. They share none, and neither does services_config.yml with
group_vars/all/main.yml, so the removal is provably inert.

services_config.yml was the last one standing. It held four unrelated things:

  caddy_sites_dir            - an identical copy of roles/caddy_site/defaults/.
                               Deleted; the role default is now the only one.
  *.tailscale_hostname (x3)  - a THIRD copy of each box's identity, which
                               inventory.ini already holds as ansible_host.
                               Deleted. Edge plays now read
                               hostvars['<host>'].ansible_host - verified an
                               edge play resolves that with nothing loaded and
                               the other host in no play. Three copies of one
                               name is how bitcoin_rpc_host ended up labelled
                               "knots_box" while pointing at fulcrum-box.
  subdomains, ntfy topic,    - genuinely global: their readers span managed,
  headscale namespace          monitoring, vpn_control and edge, so no single
                               group covers them. Moved to group_vars/all/main.yml
                               where they auto-load. The ntfy_topic and
                               headscale_namespace indirection through
                               service_settings collapses to the global name.
  the four cross-host ports  - the only entries with a real justification.
                               Left in place; they move in the next commit.

Also dead, all Uptime Kuma residue or duplication:
  phoenixd_monitor_name, forgejo_runner healthcheck_timeout_seconds/retries,
  fulcrum_tailscale_hostname, and bitcoin_knots_version - the last being a
  v-prefixed copy of bitcoin_knots_version_short that nothing read, two
  hand-maintained copies of one version string.

Corrected a false comment: services_config.yml claimed the uptime_kuma subdomain
"no longer resolves to anything". It resolves to 164.92.239.72 and answers HTTP
302, and 11 playbooks still template it. Same wrong premise as PLAN_3.

Verification: all 37 playbooks' --list-tasks output is byte-identical before and
after. A probe resolving all 22 values services_config.yml used to supply returns
21 identical and one intended deletion (caddy_sites_dir, now role-only - confirmed
the role still resolves it: "Ensure Caddy sites-enabled directory exists" comes
back ok against the real path). memos check-diff identical before and after.
Syntax passes on every playbook.

ntfy-emergency-app, vaultwarden, forgejo: use the caddy_site role
The plain reverse_proxy shape. All three removed a byte-identical 23-line
block (verified by md5 of the diff with the service name normalised) and
gained the same 7-line include_role call. The caddy_sites_dir self-reference
goes with it.

Verified in check mode, nothing applied to the hosts yet:
  - ntfy-emergency-app: site task ok, changed=0
  - vaultwarden: site task ok; the one changed task is a pre-existing
    always-restarts fail2ban step, identical before the edit
  - forgejo: check mode cannot run this playbook at all - get_url does not
    download in check mode so the next task fails on "Source /tmp/forgejo not
    found". Confirmed identical before the edit. Covered instead by the
    Stage 2 dry-run, which ran the role against vipy with forgejo's real
    parameters and reported ok/unchanged.

All 14 site files on all 3 hosts still byte-identical. Real runs for these
three are still outstanding.

uptime-kuma: add uptime_kuma_enabled flag and make monitoring blocks inert
Removing the credentials would otherwise break these playbooks mid-deploy: they
template uptime_kuma_password with no assert to stop them first. 100 tasks are
now guarded by uptime_kuma_enabled (false), so deployments run normally and the
monitoring sections skip. A further 28 tasks were already self-guarding on
monitor_setup/push_url being defined; verified that a skipped task's registered
variable makes those skip cleanly rather than error.

The blocks are kept on purpose — the health-check logic is the durable part and
should be rewired to whatever replaces Uptime Kuma.
