kevinveenbirkenbachandClaude Opus 5 e3e81e816f refactor(healthcheck): declare probes in services.yml, render them from one lookup
Seven include templates under sys-svc-container decided how a container was
probed, and they read their inputs from template-local `{% set %}` scope.
That scope leaks: a value set for one service silently reached every service
below it, which is how taiga's front and gateway ended up probing a port
declared for a different service, and how bluesky's frontend probed a PDS
endpoint.

Probes now live in utils/docker/healthcheck.py, one class per flavor behind a
PROBES registry, and each service declares its own:

    healthcheck:
      flavor: curl
      path: health/ready
      start_period: 20m

`port_key` picks another entry under ports.internal for the services that
expose their probe elsewhere (keycloak on management, nextcloud talk on
signaling). Without a flavor the entry must carry an explicit test argv, so a
missing declaration fails loudly instead of rendering a probe against nothing.

Rendering HEAD's templates against the new output confirms 49 of 56 call
sites are byte-identical; the remaining seven are covered by an Ansible run.
Three probes change on purpose: erpnext's backend gains a check it never had,
bluesky's frontend drops the leaked PDS path, and msmtp_curl moves from a
hardcoded localhost:80 to the service's own port on 127.0.0.1 like every
other flavor.
