v2.5.0: Phase 3 — weekly report, chart hover, clock-in distribution, leave calendar

- Weekly auto report on Monday (system alert + Discord push, dedupe)
- Matplotlib chart hover annotation for daily hours
- Clock-in time distribution histogram (30-min bins) with avg line
- Leave usage calendar with color-coded full/half/quarter days

Fixed: leave_view setLayout indentation regression
