feat: Enhance message handling for drawings

- Added properties to the Message model to track drawing status and associated drawing ID.
- Updated AppProvider to mark messages as drawings and link them to their respective drawing IDs.
- Enhanced DrawingProvider to manage received drawings and their visibility.
- Implemented navigation to drawings in MapProvider, including dynamic zoom levels based on drawing size.
- Updated MessagesProvider to parse drawing messages and manage linked drawings.
- Enhanced MessagesTab to support drawing message interactions, including navigation and coordinate copying.
- Created DrawingMinimapPreview widget for visual representation of drawings in message bubbles.
- Improved DrawingToolbar to handle sharing of drawings, ensuring only unshared drawings are sent.
- Added utility functions in DrawingMessageParser for extracting drawing metadata.
