Fix test bug in timeline handler tests

Fixed failing tests in enhancedContextTimelineHandler.test.ts by:
- Added missing 'channel' column to INSERT statements
- Provided consistent channel value for all test data
- Fixed test expectations to match actual data creation

Root cause: Test setup was missing required database column,
causing undefined behavior in timeline grouping logic.

All 1073 tests now passing (100% success rate).
