fix(docker): tighter healthcheck cadence with start-period

Traefik filters containers that are 'unhealthy' or still 'starting'
(no health result yet). The old 30s interval meant kochwas stayed in
'starting' for 30+ seconds after boot, blocking Traefik from routing to it.

New timing:
  --start-period=20s      grace window — failures don't mark unhealthy yet
  --start-interval=2s     fast probes during start-period
  --interval=15s          steady-state cadence after first success
  --timeout=5s, retries=3 unchanged

Container becomes 'healthy' within ~2-5s of the app coming up, so Traefik
picks it up almost immediately after 'docker compose up'.
