Implement Owner Panel features and maintenance mode handling

- Introduced the Owner Panel with new routes and UI components for managing guilds, user blacklists, feature flags, and bot presence.
- Added maintenance mode functionality to prevent non-owner users from executing commands during maintenance periods.
- Enhanced localization with new keys for Owner Panel features in both English and German.
- Updated job processing to include a presence refresh job, ensuring the bot's status is regularly updated.
- Improved environment configuration to support owner user IDs for access control.
