refactor: uniformize TextSettings styling and integrate Coloris

- Wrap all field sections in .settings-subsection divs to match PageSettings structure
- Properly nest margin outer and inner collapsed sections within their parent subsections
- Replace custom color picker with Coloris integration for color and background fields
- Simplify reactive state by removing unused format and picker properties
- Initialize Coloris with dark theme, alpha support, and format toggle
