feat: Add support for offline vector maps using MBTiles

- Introduced new MapLayerType for vector MBTiles.
- Enhanced MapLayer class to handle vector-specific properties.
- Implemented MBTilesService for managing MBTiles files, including import and deletion functionalities.
- Updated MapManagementScreen to allow importing and managing MBTiles files.
- Added UI components for displaying and interacting with MBTiles layers.
- Integrated vector tile rendering in MapTab, supporting dynamic theme loading.
- Updated pubspec.yaml to include necessary dependencies for MBTiles and vector tiles.
