Add cloud-init image building functionality to eMMC provisioning dashboard: implement API for downloading the latest Raspberry Pi OS Lite, injecting cloud-init files, and updating UI for cloud-init image creation. Enhance backup options with compression support for raw .img files using PiShrink, and update documentation to reflect new features and usage instructions.

For each raw `.img` backup you can click **Shrink** (PiShrink) or **Compress** (shrink + xz) to reduce size.
- **Build cloud-init image**: Download the latest Raspberry Pi OS Lite (arm64) from the official repository and inject cloud-init NoCloud files so the image is ready for first-boot configuration. The result appears in the backups list; set it as golden to deploy. *Requires* loop devices and mount (if the dashboard runs in an LXC, the container may need privileged mode or loop support).
- **Recent log**: Tail of the flash log (from the host, via the shared bind mount).
The dashboard reads `/var/lib/cm4-provisioning/status.json` and `flash.log`, which the flash script (running on the Proxmox host) updates. When the dashboard runs inside the LXC, that directory is bind-mounted from the host, so it sees the same files.
