fix: Correct ActiveOperationsResponse handling in useCrawlUrlV2

- Fixed missing count and timestamp fields in optimistic updates
- Preserve all ActiveOperationsResponse fields when updating progress IDs
- Fixed incorrect field comparison (source_id vs id) when replacing temp IDs
- Added query invalidation for progress queries in v2 implementation
- Ensures proper data shape consistency with backend API

These fixes ensure that:
1. ActiveOperationsResponse always has required count/timestamp fields
2. Optimistic entities are correctly matched and updated with real IDs
3. Progress queries are properly refreshed after crawl starts
