feat: Implement rulesets and layout management for kiosk plugin

Browse Source 
- Added rulesets manager to handle various data types and updates via HTTP and WebSocket.
- Introduced layout store for managing kiosk layouts with caching and server synchronization.
- Enhanced dashboard and data routes to support new layout and ruleset features.
- Updated kiosk HTML and JavaScript to utilize new layout rendering and data binding.
- Removed obsolete map route and integrated map functionality into the new tile renderer.
- Improved Telegram commands to reflect changes in data structure and logging.
- Refactored weather fetching intervals to prevent multiple instances.
- Added SSE stream for real-time layout updates in the kiosk.
