Title: Enhance the Drawing Feature with Offline Support and More Tools

Description:

Is your feature request related to a problem? Please describe.
The current drawing feature, implemented in client/src/components/drawing/DrawingEditor.tsx, provides basic real-time collaboration, which is a great start. However, it lacks more advanced functionalities that would make it a truly powerful tool for users. Key missing features include the ability to draw offline, save and load drawings, and a wider variety of drawing tools.

Describe the solution you'd like
I propose enhancing the drawing feature by adding the following capabilities:

• Offline Support: Users should be able to continue drawing even if their internet connection is lost. Once the connection is restored, their changes should be automatically synced with the other users in the room. This would make the feature more robust and user-friendly.
• Save/Load Drawings: Users should be able to save their drawings to a file (e.g., as an SVG or PNG) and load them back into the editor later. This would allow them to persist their work and continue it at a later time.
• Expanded Drawing Tools: The current toolset is quite basic. Adding more advanced tools would greatly improve the user experience. Some ideas for new tools include:
  • Different brush types (e.g., pencil, marker, calligraphy)
  • A wider variety of shapes (e.g., circles, triangles, stars)
  • A color picker with a broader palette
  • A text tool for adding annotations

Describe alternatives you've considered
We could leave the drawing feature as it is, but this would mean missing out on an opportunity to make it a much more compelling part of the application. The suggested enhancements would significantly increase its utility and appeal.

Additional context
These improvements would transform the drawing feature from a simple novelty into a powerful and practical tool for collaborative design and whiteboarding. This would add significant value to the application as a whole.
