test(agents): add validation tests for category and display fields

Added comprehensive unit and API tests to validate AgentType category and display fields:
- Category validation for valid, null, and invalid values
- Icon, color, and sort_order field constraints
- Typical tasks and collaboration hints handling (stripping, removing empty strings, normalization)
- New API tests for field creation, filtering, updating, and grouping
