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.

forgejo-runner: convert to a role, de-Uptime-Kuma the health check
409-line playbook becomes a 16-line playbook plus a 318-line role with phases
split across tasks/{prerequisites,install,configure,service,healthcheck}.yml and
four templates. forgejo_runner_vars.yml is deleted; its content is the role's
defaults.

Applies the Plan 6 Stage 0 decision: keep whatever determines whether the
service is healthy, drop the Uptime Kuma specifics, make the reporting point
pluggable. Gone from the role: the embedded Python that created monitors over
the Kuma API, the /tmp credentials file, token extraction, the systemd
Environment= rewrite, and 8 `when: uptime_kuma_enabled` guards. What remains is
the check itself, its log, the systemd unit and timer, and an honest exit code -
`systemctl is-failed forgejo-runner-healthcheck.service` now answers the
question with no monitoring system involved at all.

Reporting is one variable, healthcheck_push_url, empty by default. Any endpoint
that accepts an HTTP ping plugs in there. A pull-based monitor wants it left
empty and reads unit state instead.

PREMISE CORRECTION: Uptime Kuma is NOT dead. Plan 3 recorded "48 push timers
curling an endpoint that no longer answers" and Plan 6 said the check had
"nowhere to report to". Both wrong - 24+ push scripts across 11 hosts are
pushing successfully right now (HTTP 200). Only the Ansible code and the vault
credentials were decommissioned; the service never stopped. So the existing push
URLs were harvested into a vaulted healthcheck_push_urls dict and are preserved,
keeping this refactor behaviour-neutral. Retiring Kuma stays a deliberate act
rather than a side effect. PLAN_3 and PLAN_6 are corrected.

Verified:
  - task-list diff vs the old playbook shows ONLY the five Kuma tasks removed,
    everything else identical and in the same order
  - first run ok=22 changed=1 (the rewritten health script); both systemd units
    and forgejo-runner.service came back ok, so the templates reproduce the
    previous files byte-for-byte
  - second run ok=22 changed=0, fully idempotent
  - still reports "Ping sent successfully (HTTP 200)" from a script containing
    zero Uptime Kuma references
  - the 4 skipped tasks are genuine already-configured guards, checked not assumed

Two things for the next service:

- import_tasks, not include_tasks. Dynamic includes are opaque to --list-tasks,
  which is the primary verification tool here; the first attempt produced a
  useless diff.
- `Assert runner is running` was guarded by uptime_kuma_enabled and so had not
  run since the decommissioning. It is not monitoring, it is the deployment
  checking its own work - the deprecation banner swept it up with the Kuma
  plumbing, and a runner that failed to start was deploying "successfully" in
  silence. Ungated now. The banner was applied to contiguous blocks, so read
  every uptime_kuma_enabled guard and ask whether it is monitoring or deployment.
