feat(ui): add int slider support and fix update_text_scale calls

- Add `set_text()`, `set_track_image()`, `set_thumb_image()` methods.
- Include label rendering and auto-scaling based on slider dimensions.
- Replace static `THUMB_WIDTH` with dynamic thumb sizing.
- Add slider thumb and track texture assets.
