+This macro caps a given value between a specified bottom and top limit,
+returning `NULL` if the input value is `NULL`.
+
+It uses the `LEAST` and `GREATEST` SQL functions to enforce the caps while 
+preserving the `NULL` values in the input.
+
+Parameters:
+- `value`: The value to be capped.
+- `cap_bottom`: The minimum limit for the value.
+- `cap_top`: The maximum limit for the value.
