The learning-platform (Caddy) container crash-looped since this morning's
89d3395: `Content-Type application/json` is not a valid subdirective of
`respond` — a Caddyfile parse error aborts Caddy at startup, taking the
whole app offline for authenticated users while every CI run stayed green.
Verified with caddy v2.10.0: "unrecognized subdirective 'Content-Type',
at Caddyfile:53"; the fixed file validates clean.
CI was blind to this twice over: test.yml swaps the real Caddyfile for
Caddyfile.test in the test image, and the deploy health-gate from #18
only covers PocketBase.
- Caddyfile: set Content-Type via a `header @api` directive before the
`respond`; behaviour of the JSON error response is unchanged
- infra/*/site/deploy-playbook.yml: frontend health-gate (docker exec
wget --spider on the container) with log dump + abort on failure, and
an always-on post-deploy smoke report (compose ps, proxy health,
team_members auth-methods, PocketBase log tail) for visibility behind
the auth perimeter
Closes#20
