Viktor Barzin 047a1189c9 backup-dr docs: refresh diagrams for daily/immich-only architecture
- Add new "Data Routing" flowchart up front showing which paths go
  where (sda mirror vs Synology-direct vs not-backed-up).
- Overall Backup Flow: split Layer 2 into 2a (nfs-mirror daily 02:00)
  and 2b (daily-backup 05:00); show nfs-mirror as an explicit
  component; clarify Step 2 is immich-only direct + nfs-ssd.
- Weekly Backup Timeline → Daily Backup Timeline: actual schedule
  (00:00 LVM, 00:15 PG, 00:45 MySQL, 02:00 nfs-mirror, 05:00 daily-
  backup, 06:00 offsite-sync, 12:00 second LVM); explicit inotify
  feeding Step 2.
- Physical Disk Layout: current capacity numbers + dual sdc→sda and
  sdc→Synology arrows (immich-only) reflecting the two-leg design.
- Restore Decision Tree: refreshed age tiers (< 12h LVM, 12h-4w sda,
  > 4w Synology) + dedicated branch for immich photos (which only
  have an offsite copy).
