StatusBadge: simplify to 5 basic categories (正常/異常/缺勤/公假/請假)

- StatusBadge no longer shows detailed late/early/OT minute breakdowns
  nor AL/SL/CL sub-types; collapse to single basic-status badge
- List page: replace text-input column filter with status dropdown
  (server-side ?status_text= filter; backend now supports 'leave' IN-clause
  for al/sl/cl/mixed_leave group)
- List page: badge now driven by backend status_code/status_text
  (remove frontend latenessMap which contradicted backend status)
