Cache validity now checks _last_coordinator_update (within 30min) instead of _api_calls_today counter. Fixes false "stale" status when coordinator runs every 15min but cache validation was only checking API call counter. Bug #1: Cache validity shows "stale" at 05:57 AM Bug #2: Cache age calculation incorrect after midnight turnover Bug #3: get_cache_validity inconsistent with cache_age sensor Changes: - Coordinator: Use _last_coordinator_update for cache validation - Lifecycle: Extract cache validation to dedicated helper function - Tests: 7 new tests covering midnight scenarios and edge cases Impact: Cache validity sensor now accurately reflects coordinator activity, not just explicit API calls. Correctly handles midnight turnover without false "stale" status.
