feat: add OllamaLocalExecutor and update provider handling

- Introduced OllamaLocalExecutor to handle requests for the "ollama-local" provider.
- Removed the direct URL construction for "ollama-local" from BaseExecutor.
- Updated index.js to include the new OllamaLocalExecutor in the executors mapping.
- Enhanced the ProvidersPage component to support dynamic addition of OpenAI/Anthropic compatible providers.
