Kevin Veen-Birkenbach 05d7ddc491 svc-bkp-rmt-2-loc: migrate pull script to Python + add unit tests; lock down backup-provider ACLs
- Replace Bash pull-specific-host.sh with Python pull-specific-host.py (argparse, identical logic)
- Update role vars and runner template to call python script
- Add __init__.py files for test discovery/imports
- Add unittest: tests/unit/roles/svc-bkp-rmt-2-loc/files/test_pull_specific_host.py (mocks subprocess/os/time; covers success, no types, find-fail, retry-exhaustion)
- Backup provider SSH wrapper: align allowed ls path (backup-docker-to-local)
- Split user role tasks: 01_core (sudoers), 02_permissions_ssh (SSH keys + wrapper), 03_permissions_folders (ownership + default ACLs + depth-limited chown/chmod)
- Ensure default ACLs grant rwx to 'backup' and none to group/other; keep sudo rsync working
