fix: resolve remaining integration test failures

- Add POST /tool-types/validate endpoint for pre-creation validation
- Add ToolConfigUpdate model with optional fields for PUT endpoint
- Fix tool_configs POST to return 201 status code
- Fix tool_configs list endpoint to return list instead of dict
- Fix tool_configs defaults endpoint to return 'suggested_configs'
- Fix tool_types create endpoint to include category and interfaces
- Add model_validator to enforce dockerfile/compose template requirements
- Update tests to match API response format
