feat: B5 — port retention/template-backup to Python, deploy systemd timers

Browse Source 
- Add `retention run` command (ports Invoke-RetentionPolicy.ps1): purges
  old artifact/log dirs with aggressive mode when disk space is low.
- Add `template backup` command (ports Backup-CITemplate.ps1): 7z -mx=1
  compressed archives in /var/lib/ci/backups/, prunes to keep-count=3,
  stops/restarts act-runner.service around the copy.
- Update ci-retention-policy.service and ci-backup-template.service to use
  Python; pwsh is no longer required on the Linux host.
- Fix ci-watch-runner-health.service: pass --service-name act-runner
  (Linux service name, not Windows act_runner default).
- Fix _list_orphans in vm.py: wrap is_dir() inside the OSError try block
  so a stat() failure on an entry is silently skipped rather than raised.
- Mark B5 complete in PhaseB-user-checklist.md.

## Nota PowerShell su Linux
Due unit (`ci-retention-policy`, `ci-backup-template`) invocano script
PowerShell che, per scelta documentata in `AGENTS.md` ("Mappatura script
PowerShell → Python"), restano in PowerShell. Su Linux questo richiede
**PowerShell Core (`pwsh`)**:
```bash
# Ubuntu / Mint LTS
sudo apt-get update
sudo apt-get install -y wget apt-transport-https software-properties-common
wget -q https://packages.microsoft.com/config/ubuntu/$(lsb_release -rs)/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install -y powershell
pwsh --version # verifica
```
Se preferisci non installare `pwsh`, porta `Invoke-RetentionPolicy.ps1` e
`Backup-CITemplate.ps1` come sub-comandi `python -m ci_orchestrator
retention run` / `template backup` (out of scope B5 per il piano corrente
— vedi `plans/implementation-plan-A-B.md`).
