fix(attendance): admin month view no longer truncates at 100 records

The KPI cards and on-screen summary totals (computeUserTotals) are computed
client-side from one month fetch. The hook requested limit=1000 but
parsePagination silently clamped it to 100, so once a month exceeded 100
attendance rows (~5 employees x 21 shifts) the newest-first list dropped the
EARLIEST days of the month — screen totals undercounted while the print path
(complete server fetch) stayed correct. This is the data-volume cliff that
made the summary counting look like it changed without any formula change:
git archaeology confirms every counting formula is bit-identical from v1.9.1
through HEAD.

- routes/admin/attendance.ts: list endpoint passes maxLimit 2000 to
  parsePagination (complete-month view; 2000 ~ 64 employees x 31 days)
- useAttendanceAdmin: month fetch requests limit=2000 with the constraint
  documented
- regression test: a 120-row month returns all 120 records
