- Added a shared XTextColor definition and a palette conversion helper for Cairo-ready colors, decoupling renderer palettes from GdkColor usage in the API surface.

- Updated xtext palette APIs to accept internal color arrays directly for rendering setup.
- Wired xtext palette creation through UI entry points to use the new palette helper when constructing or refreshing text views.
