- Added keyboard classes (Keyboard, EmulatedKeyboard, UnicodeKeyboard) from example.html
- Added mouse event handling functions
- Integrated WebAssembly module loading and RDP client setup
- Added event listeners for canvas focus, keyboard, and mouse events
- Fixed RDP connection flow to match example.html structure
- Added proper input handling and keyboard layout support
- Implemented canvas event management for proper user interaction

This should resolve the RDP connection issue where it was stopping at negotiation phase due to missing user input handling.
