Replace embedded heredocs in the three backup service installers with
cp from versioned source files in extras/:
extras/backup_kopia.sh — Kopia worker (was inline in services/backup.sh)
extras/backup_borg.sh — Borg worker (was inline in services/borg-backup.sh)
extras/backup_gaming.sh — gaming saves worker (was inline in services/gaming-backup.sh)
extras/restore_kopia.sh — unified Kopia restore (multi-dest + single-dest)
extras/restore_borg.sh — unified Borg restore with destination picker
Each installer now does `cp extras/<script>.sh $DIR/<script>.sh` instead of
writing the script inline. Workers and restore scripts are now readable in the
repo rather than buried in heredocs.
Restore scripts are installed flat into the service directory root:
~/docker/backup/backup_kopia.sh ~/docker/backup/restore_kopia.sh
~/docker/borg-backup/backup_borg.sh ~/docker/borg-backup/restore_borg.sh
~/docker/gaming-backup/backup_gaming.sh ~/docker/gaming-backup/restore_kopia.sh
The new restore scripts handle destination selection internally, so a single
script replaces the old per-destination restore/<dest>/ layout.
Also fixes `local` used outside a function in restore_kopia.sh and
restore_borg.sh (destination picker loop), and removes the now-superseded
extras/restore_kopia_backup.sh and extras/restore_borg_backup.sh.
