Rename DynamicModelCatalog to FallbackModelCatalog

The class has been renamed from DynamicModelCatalog to FallbackModelCatalog to better reflect its purpose as a fallback catalog that accepts any model name when a specific catalog is not available.

Updated all references across the codebase including:
- Test files and test cases
- Bridge implementations (OpenRouter, HuggingFace, LmStudio, TransformersPhp)
- Test utilities (InMemoryPlatform, ModelCatalogTestCase, PlatformTestHandler)
- Comments and documentation
