Backup was mostly working but failing at the end due to Python calls.
CHANGES:
- Made manifest generation work without Python (bash JSON)
- Made check verification recording work without Python
- All Python calls now wrapped in 'command -v python3' checks
- Falls back to bash sed for JSON updates
RESULT: Backup completes successfully without Python
- Database dump: SUCCESS (24K)
- Minimal manifest: SUCCESS (bash-generated JSON)
- Restic snapshot: SUCCESS
- Repository verification: SUCCESS
- Script exit: SUCCESS (no more Python errors)
Backups now work in offline/corporate proxy environments with
zero downloads during Docker build.
