Privacy/space housekeeping for the kiosk verification selfies. A new daily cron
(_cron_fusion_wipe_old_photos) deletes the photo attachments on attendances
whose clock-in is older than fusion_clock.photo_retention_days (default 60).
Only the images are removed — attendance records, worked hours and penalties
are kept. Clearing the attachment-backed binary reclaims filestore space.
- Configurable in Settings → Fusion Clock → NFC Kiosk ("Auto-Wipe Photos After
(days)"); set 0 to disable.
- Wipes all three photo fields (NFC check-in/out + legacy portal photo),
batched with per-batch savepoints.
- tests/test_photo_retention.py covers wipe-old / keep-recent / retention=0.
Verified live on entech (19.0.3.11.7) via a rollback-only dry run: a 70-day
shift's photos were wiped (record + 8h hours preserved) while a 5-day shift's
photo was kept; nothing persisted. 0 attendances currently exceed 60 days.

Adds the NFC card UID field (Char, unique, manager-only) that the kiosk
will use to identify employees by card tap. Includes the tests package
with three post-install tests covering write, uniqueness, and nullable
multi-row behaviour.
