Add drawing sharing functionality and localization updates

- Implemented sharing options for drawings, including sharing to a public channel and specific rooms.
- Added confirmation dialogs for deleting drawings and sharing drawings.
- Enhanced the drawing toolbar to display a list of user's drawings with options to share or delete.
- Updated localization files for English, Spanish, French, Croatian, Italian, German, Slovenian, and other languages to include new strings related to drawing sharing and management.
- Introduced syncing of drawing messages with the DrawingProvider to restore missing drawings.
- Improved the drawing minimap preview to display a small preview of drawings in the toolbar.
