Julian Pawlowski	1d065b11cd	fix(services): use injected now in resolve_search_range day offset ... _resolve_time_with_day_offset() was calling dt_util.now() internally instead of using the injected now parameter. This caused incorrect date calculations in tests and any caller that passes a specific reference time. Also add missing price_rank_* sensor keys to TIME_SENSITIVE_ENTITY_KEYS in coordinator/constants.py so quarter-hour refresh is registered for all 11 price rank sensors (current/next/previous interval and hour variants). Rename dt as dt_utils → dt as dt_util (ICN001) across 11 files to follow the project-wide import alias convention. Apply ruff auto-fixes for import ordering and collapsing single-item imports throughout the codebase. Released-Bug: no	2026-04-14 19:33:24 +00:00

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
