Refactor model handling and deduplication logic in settings service

- Updated ModelDropdown to use option names directly instead of model names.
- Introduced canonicalModelNameForProvider to standardize model names across providers.
- Implemented deduplication of provider models to avoid duplicates and manage aliases effectively.
- Enhanced model fallback logic in modelCapabilities for better compatibility with new AI models.
- Adjusted settings service to incorporate deduplication and normalization of model names.
