Add git repository selection for panel updates

- Add repository URL setting to panel_settings table
- Support for multiple git hosting providers (GitHub, Gitea, GitLab, etc.)
- UI selector for predefined repositories (git.tzim.uz and github.com) or custom URL
- Update service now uses repository from database settings
- API endpoints: GET/PUT /api/updates/repository
- Migration for default repository setting
- Translations for repository selection UI
