fix: HA checks resolve service targets over project network; persist checks (#13)
- Health checks for local services dialed 127.0.0.1 from inside the backend
  container — the host's published port is unreachable there. Service-bound
  checks now resolve the service's DNS name on its project network (backend
  joins on demand), falling back to the service's stored port. A resolver
  failure surfaces as TARGET_UNRESOLVED instead of a fake loopback probe.
- Checks lived only in memory: a backend restart silently deleted every
  configured health check. ha_health_checks table + write-through on
  add/update/tick and hydrate-on-boot, matching the scaling-policy pattern.
- sqlc schema.sql gained the runtime columns added by later migrations —
  the stale snapshot already caused one silently-dropped-column bug.
- OpenAPI: runtime response now documents ports and health fields; types
  regenerated.
- Buttons no longer wrap ("+ new project" rendered on two lines).

Verified live: service check probes whoami-web:80 via DNS → healthy;
check survives a backend restart and rehydrates.
