- Add Europe/Oslo timezone to all DateTime constructors in getAvailableTimes() and
computeLunchBreak() to prevent UTC vs local time mismatch that allowed booking
slots 1 hour past the worker's end time on same-day bookings
- Remove fallback loop in computeLunchBreak() that pushed the lunch break outside
the configured window; lunch break is now strictly enforced within the interval
