fix(push): log every silently swallowed error

Three silent catches in the push pipeline made today's APNS_KEY=12-char
secret outage take hours to diagnose. Each one swallowed an exception
without a single log line, leaving 78 server with "Relay 502" but the
K8s pod logs completely empty:

- push.ts relay route: importPKCS8() throw was caught and turned into a
  502 JSON response with no log
- bridge.ts dispatchEventPush: dynamic import failure (e.g. missing prod
  dep) silently disabled all push notifications
- push.ts dispatchPush: badge_count UPDATE failure was a bare catch

All three now log via the existing pino logger so the next failure
surfaces immediately in `kubectl logs` instead of silently dropping
notifications.
