Fix Ncurses click handling and restore ncursesw build

This commit addresses issues with mouse interaction reliability and build configuration in the Ncurses renderer and example.

Renderer Changes:
- Enable explicit xterm 1003 mouse tracking (Any Event) via escape sequences to ensure reliable hover sensing from the first frame (though not so portable).
- Refactor `Clay_Ncurses_ProcessInput` to:
  - Correctly order `Clay_SetPointerState` calls to ensure the "Pressed" state is registered before the function returns.
  - Detect and return a new `CLAY_NCURSES_KEY_MOUSE_CLICK` event code for single, double, and triple clicks.
- Make `Clay_Ncurses_OnClick` as a semantic wrapper around `Clay_OnHover`.
- Add empty switch cases for `CLAY_RENDER_COMMAND_TYPE_IMAGE` and `CLAY_RENDER_COMMAND_TYPE_CUSTOM` to prevent unhandled enumeration warnings.

Example Application Changes:
- Update `main.c` to break the input processing loop immediately upon receiving `CLAY_NCURSES_KEY_MOUSE_CLICK`, ensuring the "Pressed" state is processed by the layout engine for that frame.

Build System:
- Update `CMakeLists.txt` to replace `FindCurses` with `find_library` and `find_path` for `ncursesw`.
