Bump version 1.2.0 → 1.3.0

Status & filter improvements consolidated:
- StatusBadge: 5 basic categories + leave suffix chip
- Backend filter: enrich-then-filter so badges match result set
- 請假/公假 filter: also match leave/holiday suffix in status_text
- Rest day detection: roster rest weekday → 休息 (not 缺勤)
