Add database foundation for observability features:
- event_log table with severity/source filtering and pagination
- standalone_proxies table for user-created reverse proxies
- stale_threshold_days setting (default 7 days)
- Auto-persist warn/error events from event bus to database
- SSE broadcast of persistent events for real-time UI updates
- Frontend types and API functions for downstream UI phases
When the SSL certificate is changed in settings, automatically
updates all existing NPM proxy hosts managed by Docker Watcher
in the background. Clears SSL if cert is removed.
Remove webhook secret from logs and API response.
Add auth-pending note to router. Fix decrypt fallback that
would use ciphertext as auth token on decrypt failure.
All REST endpoints wired with chi router: projects, stages, instances,
deploys, registries, settings, quick deploy, webhook. Full main.go
wiring with graceful shutdown. Consistent JSON envelope responses.
Sensitive fields stripped from API responses.
