tests: Add unit tests for browse_events, fetch_all_pages, filter_events, is_match_market, get_ml_market, get_ml_volume, sort_events

New test classes:
- TestIsMatchMarket: 5 tests for is_match_market() classification
- TestGetMlMarket: 5 tests for get_ml_market() and get_ml_volume()
- TestFilterEvents: 5 tests for filter_events() and sort_events()
- TestFetchAllPages: 4 tests for fetch_all_pages() early-exit logic
- TestBrowseEvents: 5 tests for browse_events() sort_by parameter

Total: 24 new tests (62 total, all passing)
