Madhura68 ab87c0fada feat(server-backup): restic dual-repo backup (NAS + B2) with dashboard UI
Adds a server-wide backup capability beyond the existing ops_dashboard
pg_dump flow:

- Daily systemd timer (03:30) runs pg_dumpall + Forgejo dump, then restic
  to a local NAS repo and an offsite Backblaze B2 repo with Object Lock.
  Phase-based script with single-instance flock, structured statusfile,
  systemd hardening, and live-datadir excludes (Postgres / Forgejo) so
  the dumps stay authoritative.
- Ops-agent gets nine new read-only/trigger commands (snapshots, stats,
  status, logs, plus two triggers) backed by sudoers-whitelisted wrapper
  scripts that source /etc/restic-backup.env so the agent never sees the
  restic password or B2 keys.
- Two new flows (server_backup_full, server_backup_restore_test) drive
  the dashboard's "Backup now" and "Restore test" buttons.
- /settings/backups gains a Server backup section with overall + per-phase
  status, NAS / B2 snapshot tables, restore-size / raw-data / dedup-ratio
  stats, and the last restore-test result. The existing pg_dump section
  is preserved unchanged.
- Runbook docs/runbooks/server-backup.md follows the tailscale-setup
  pattern (plan + addendum) and covers B2 Object Lock + scoped keys,
  Forgejo subplan with isolated restore-test stack, the off-server
  maintenance flow for B2 prune, and the integrity-check schedule.

Code-only change — installation on scrum4me-srv follows the runbook.
