* feat: Add relative mouse mode
- Add "Relative Mouse Mode" toggle in desktop toolbar and bind to InputModel
- Implement relative mouse movement path: Flutter pointer deltas -> `type: move_relative` -> new `MOUSE_TYPE_MOVE_RELATIVE` in Rust
- In server input service, simulate relative movement via Enigo and keep latest cursor position in sync
- Track pointer-lock center in Flutter (local widget + screen coordinates) and re-center OS cursor after each relative move
- Update pointer-lock center on window move/resize/restore/maximize and when remote display geometry changes
- Hide local cursor when relative mouse mode is active (both Flutter cursor and OS cursor), restore on leave/disable
- On Windows, clip OS cursor to the window rect while in relative mode and release clip when leaving/turning off
- Implement platform helpers: `get_cursor_pos`, `set_cursor_pos`, `show_cursor`, `clip_cursor` (no-op clip/hide on Linux for now)
- Add keyboard shortcut Ctrl+Alt+Shift+M to toggle relative mode (enabled by default, works on all platforms)
- Remove `enable-relative-mouse-shortcut` config option - shortcut is now always available when keyboard permission is granted
- Handle window blur/focus/minimize events to properly release/restore cursor constraints
- Add MOUSE_TYPE_MASK constant and unit tests for mouse event constants
Note: Relative mouse mode state is NOT persisted to config (session-only).
Note: On Linux, show_cursor and clip_cursor are no-ops; cursor hiding is handled by Flutter side.

1. Update kcp-sys to send KCP in frames to avoid potential crashes.
2. Fix the issue when the controling side is closed, the kcp connection close is not immediately recognized by the controlled end.
* Unless the controling side receives the close reason, force the sending of the close reason to the controlled end when using KCP, and delay for 30ms to ensure the message is sent successfully.
* Move the CloseReason receiving forward, as this message needs to be received when unauthorized, especially for kcp.

1. Enable the RustDesk client to use WebSocket for either controlling or being controlled.
2. Fix TCP sending `register_pk` frequently
Note:
1. Because hbb_common directly uses `use_ws` to read config directly, rustdesk also directly reads config
