fix: implement pagination for schema resource fetching

The schema resource registration was only fetching the first page of
schemas from Cordra, causing schemas beyond the page limit to not be
registered as MCP resources.

Changes:
- Enhanced find() method to support pagination with page_size/page_num
- Modified schema registration to paginate through all results
- Updated return structure to include pagination metadata
- Added comprehensive test coverage for pagination scenarios
- Maintains backward compatibility with existing code
