Fix Grafana UI freezing caused by auth token rotation loop

Root cause identified from browser Network tab:
- 1040 requests in 12 seconds
- Endless /api/user/auth-tokens/rotate calls every 7-8ms
- Runaway polling loop blocking browser main thread

Solution: Disable automatic auth token rotation
- GF_AUTH_TOKEN_ROTATION_INTERVAL_MINUTES=0

This stops Grafana from continuously polling the auth token
rotation endpoint, which was causing the browser to freeze.
