fix: Resolve pyright type errors in MCP server factories

- Add validation for Azure OpenAI API URL to ensure it's not None
- Fix OpenAI embedder config to use 'embedding_model' instead of 'model'
- Remove 'dimensions' parameter from OpenAIEmbedderConfig (not supported)
- Add URL validation for both LLM and embedder Azure configurations

All pyright type checks now pass with 0 errors.
