feat(hub): implement native in-app container updates

Introduces the ability for registered users to trigger Beszel container updates directly from the web interface.

- Added `app_update` logic to the hub to pull the latest image from GHCR and recreate the container.
- Implemented `/api/beszel/update` and `/api/beszel/update/apply` endpoints.
- Added a new `AppUpdatePanel` in the settings UI to check for and apply updates.
- Added update notifications in the navbar and settings.
- Updated `docker-compose.yml` and `README.md` to include the required Docker socket mount for update functionality.
- Added a new public status page route that bypasses authentication.
- Refactored several TypeScript interfaces to replace `any` with `unknown` or specific types for better type safety.
- Updated localization files to support new update-related strings.
