Fix timezone-dependent test failures in CI/CD pipeline

Made enhanced-context-operations.test.ts immune to timezone differences:
- Use UTC time for all date calculations and queries
- Create test data with explicit UTC timestamps
- Ensure "today" tests work regardless of local timezone

Problem: Test created data with local time but queried with local midnight,
causing failures when CI/CD runs in different timezone where items
fall on different calendar days.

Solution: Consistent UTC usage throughout test data creation and queries,
making tests deterministic and timezone-agnostic.

All 1073 tests now pass reliably in any timezone.
