refactor: remove scroll sensitivity functionality and clean up related code (#477)

- Removed scroll sensitivity state and associated functions from jsonrpc.go and WebRTCVideo component.
- Cleaned up device settings store by eliminating unused scroll sensitivity logic.
- Updated mouse settings route to reflect the removal of scroll sensitivity feature.
- Simplified mouse wheel event handling in WebRTCVideo component.
