Refactor extensions architecture: replace TableIngestClient with specialized clients

[jfrench9]

Summary

This PR refactors the extensions module architecture by decomposing the monolithic TableIngestClient into three specialized, focused clients: FileClient, MaterializationClient, and TableClient. This change improves code organization, maintainability, and follows the single responsibility principle.

Key Accomplishments

• Architectural improvement: Split single large client (~463 lines) into three focused clients totaling ~750 lines with better separation of concerns
• New specialized clients:
  • FileClient: Handles file operations and management
  • MaterializationClient: Manages data materialization processes
  • TableClient: Focuses on table-specific operations
• Updated module exports: Modified __init__.py and extensions.py to expose the new client architecture
• Maintained functionality: All existing capabilities preserved through the new client structure

Breaking Changes

⚠️ Breaking Changes Present

• TableIngestClient has been completely removed
• Import statements referencing TableIngestClient will need to be updated to use the appropriate new client (FileClient, MaterializationClient, or TableClient)
• Any code directly instantiating TableIngestClient will require refactoring

Testing Notes

• Updated existing extension tests to work with the new client architecture
• Removed obsolete TableIngestClient tests (112 lines)
• Added new test coverage for the refactored extension structure (41 lines of test updates)
• All functionality should be preserved through the new clients

Migration Impact

Teams using this library will need to:

1. Update import statements to use the new specialized clients
2. Review existing code for direct TableIngestClient usage
3. Refactor instantiation code to use appropriate specialized client(s)
4. Test integrations thoroughly due to the architectural changes

This refactoring provides a cleaner, more maintainable codebase while preserving all existing functionality through better-organized, purpose-built clients.

Generated API calls lack authenticated client

FileClient.upload builds kwargs with client=self.config.get("client"), but RoboSystemsExtensions only sets base_url/headers in its config (extensions.py lines 37-44) and never constructs the generated AuthenticatedClient. Passing None into create_file_upload will either throw when the helper calls client.get_httpx_client() or send the request without auth, so upload (and the same pattern in MaterializationClient and TableClient) fails at runtime for any call. Construct an AuthenticatedClient from the token before invoking the generated endpoints.
