fix: set TZ=Europe/Bucharest in Docker + scheduler diagnostic logs

The container was running on UTC by default — the 1-5 AM window was
actually 4-8 AM Romania time, missing the intended night window.

- Add TZ=Europe/Bucharest + tzdata package to Dockerfile
- Add startup diagnostic logs: server time, timezone, ETERRA creds check
