Julian Pawlowski	f60b5990ae	test: add pytest framework and midnight-crossing tests ... Set up pytest with Home Assistant support and created 6 tests for midnight-crossing period logic (5 unit tests + 1 integration test). Added pytest configuration, test dependencies, test runner script (./scripts/test), and comprehensive tests for group_periods_by_day() and midnight turnover consistency. All tests pass in 0.12s. Impact: Provides regression testing for midnight-crossing period bugs. Tests validate periods remain visible across midnight turnover.	2025-11-21 23:47:01 +00:00
