feat(cosmic-term): add comprehensive terminal configuration support

- Add complete configuration options for COSMIC Terminal
- Implement color scheme management with dark/light themes
- Add profile management with default profile validation
- Fix RON map key handling for numeric keys
- Add hex color type validation
- Add utilities for null-or options
- Make configuration conditional on hasSettings flag

The module now supports full configuration of COSMIC Terminal including
profiles, color schemes, font settings, and appearance options.
