feat(ci): enable maintenance mode during deployments

The deploy workflow now:
1. Enables maintenance mode before building (users see maintenance page)
2. Builds, pushes, and restarts the container
3. Disables maintenance mode after health check passes (if: always)

Uses Gitea's built-in maintenance mode via admin config API.
If the instance is already down, the enable step gracefully warns
instead of failing. The disable step runs even if deploy fails
to avoid leaving the instance in maintenance mode.
