Problem
Kopia writes cache, config and logs to the root filesystem by default.
On SD-card based Umbrel installs, this fills the root overlay (~4 GB) and
breaks built-in backups despite sufficient free space on /mnt/data.
Solution
Redirect Kopia cache, config and log directories to Umbrel’s data directory.
All required directories are created defensively before starting Kopia.
