Backup Client (PySide6)

Portable Windows client UI that drives the Proxmox FastAPI orchestrator via HTTPS.

Features

Profile management (name + folder list) stored next to the executable in config.json.
Folders list, Task Scheduler toggle, SSH credentials (username/password) for the pull backup.
Progress bar, status label and log stream fed by the orchestrator's /backup/status and /backup/log endpoints.
Login prompt when the stored API token expires or is missing.

Install dependencies (pip install -e . inside the client folder or build a PyInstaller bundle).
Launch the client: python -m backup_client.ui (PyPI-style module entry uses the main() function).
Use the UI to create/save profiles, add folders, enter the Windows host/SSH info, and click Esegui backup.
Config (server URL, profiles, scheduler flag, token) is persisted in config.json sitting beside the executable for portability.

The Task Scheduler switch is persisted but wiring to schtasks should be done via scripts.
rsync.exe, OpenSSH, and wrapper scripts live on the Windows client; this UI only triggers the server pull.
See scheduler/manage_scheduler.ps1 for a helper that takes -Action Enable|Disable, -TaskName, -ExecutablePath, and optional profile metadata to build the schtasks /Create call. The checkbox now invokes that script, so enabling the scheduler creates the ONLOGON task that calls BackupClient.exe --auto --profile "<name>" and disabling the switch removes it.
After PyInstaller finishes, run post_build.bat path\to\dist\<bundle> to copy config.json and the scheduler helper into the same directory as BackupClient.exe so the runtime can find them (post_build.bat copies config.json to the root and the scheduler folder beside the exe).
Run package_client.sh from Bash/WSL or package_client.bat from cmd/PowerShell: both invoke PyInstaller with the required --add-data flags, target dist/BackupClient, and call post_build.bat so config.json and the scheduler helper travel with the exe.
