backup: exclude /anca-elements/ from nfs-mirror + offsite Step 1

Browse source 
Anca's photos are being ingested into Immich (started 2026-05-24
afternoon), so /srv/nfs/immich/library/ becomes the canonical copy
for those photos. The separate /srv/nfs/anca-elements/ archive tree
+ its sda mirror at /mnt/backup/anca-elements/ are now redundant.

Going forward:
- nfs-mirror EXCLUDES /anca-elements/ so future weekly runs don't
  re-touch the 771G subtree (also no longer required since Immich
  has the data via its NFS library).
- offsite-sync Step 1 also excludes /anca-elements/ — the historical
  771G under /mnt/backup/anca-elements/ stays on sda for now but is
  NOT shipped to Synology pve-backup/ (Immich's library reaches
  Synology via Step 2 bypass leg anyway).

The 771G on /mnt/backup/anca-elements/ will be cleaned up manually
once Immich ingest completes and we verify all photos are in the
Immich library. Same for /srv/nfs/anca-elements/ on sdc thin pool —
freeing both would reclaim ~1.5 TB across sdc + sda.

In-flight context: today's nfs-mirror first run was killed mid-flight
at ~70% (was at /srv/nfs/postgresql/). The killed run wrote ~200G of
service NFS subtrees to /mnt/backup/<svc>/, then sda hit 95% used,
prompting this change. Next nfs-mirror run will not touch
anca-elements and will fit comfortably (~250G total for the keep-list
minus anca-elements).
