chore: Regenerate OpenAPI spec with custom theme endpoints

Regenerated the frontend API SDK to include:
- /theme/save-custom endpoint for saving custom themes
- /theme/saved/{id} endpoint for deleting custom themes
- SaveCustomThemeRequest type definition
- Updated theme presets description

This completes the custom theme saving feature integration.
