feat(monitoring): structured logging, Promtail alignment, GlitchTip config, status page

- Upgrade shared-logger to dual-mode: JSON lines in production, console
  in dev. Adds configureLogger() for service name + request ID.
- Add requestLogger middleware to shared-hono with request ID generation
  and structured request/response logging.
- Align Promtail config with new JSON field names (requestId, ts, service).
- Add PUBLIC_GLITCHTIP_DSN + PUBLIC_UMAMI_WEBSITE_ID to mana-web docker config.
- Add /status page that polls all backend /health endpoints server-side.
