feat(ui): add ComboButton widget and integrate into settings

Introduce ComboButton, a button that cycles through options on click.
Used in SettingsUI for fullscreen, V-Sync, and anisotropic filtering.
Adds texture reload support in SettingsScene and makes Button methods
virtual to allow overriding. Also fixes default mouse_enable to true.
