test(time): add boundary tolerance and DST handling tests
Added 40+ tests for TibberPricesTimeService:
Quarter-hour rounding with ±2s tolerance:
- 17 tests covering boundary cases (exact, within tolerance, outside)
- Midnight wrap-around scenarios
- Microsecond precision edge cases
DST handling (23h/25h days):
- Standard day: 96 intervals (24h × 4)
- Spring DST: 92 intervals (23h × 4)
- Fall DST: 100 intervals (25h × 4)
- Note: Full DST tests require Europe/Berlin timezone setup
Day boundaries and interval offsets:
- Yesterday/today/tomorrow boundary calculation
- Interval offset (current/next/previous) with day wrapping
- Time comparison helpers (is_current_interval)
Impact: Validates critical time handling logic. Ensures quarter-hour
rounding works correctly for sensor updates despite HA scheduling jitter.
