MechaCat02 40c6fd2ccb fix(deploy): unblock production bring-up (healthchecks + Caddy DOMAIN) ...

Two issues would each stop a clean production `docker compose up` for the event:

1. Healthchecks probed http://localhost:{3000,3001}, but the app and frontend
   bind IPv4 (0.0.0.0) while `localhost` resolves to ::1 (IPv6) first inside the
   container — so the probe got "connection refused" and neither container ever
   turned healthy. Caddy is gated on `condition: service_healthy` for both, so on
   a fresh boot it would block forever and nothing gets served. Switch both probes
   to 127.0.0.1. (Verified: both containers now report healthy.)

2. The prod caddy service never received DOMAIN, so the Caddyfile's `{$DOMAIN}`
   site address expanded to empty — malformed site block, no TLS, no serving. Add
   `environment: { DOMAIN: ${DOMAIN} }` to the caddy service.

Also make .env.example honest and event-ready:
- Add DATABASE_MAX_CONNECTIONS (real env lever; recommend 30 for ~100 guests).
- The DEFAULT_* upload/rate/capacity vars are NOT read from env — they are seeded
  into the DB config table and managed at runtime via the admin dashboard. Replace
  the misleading entries (e.g. upload rate showed 10; live value is 100 via
  migration 015) with a note pointing to the admin UI and the real seeded defaults.
- Document that raising COMPRESSION_WORKER_CONCURRENCY also needs the app memory
  limit raised (ffmpeg), so a video burst can't OOM the box.
