luci: generated backup archive is not directly restorable #8253
Description
Is there an existing issue for this?

Actual behaviour
When generating a configuration backup via:
LuCI → System → Backup / Flash Firmware → Actions → Generate archive
the resulting archive is a plain .tar file. Attempting to restore this
archive via the LuCI restore function fails.
If the same archive is manually recompressed to .tar.gz, the restore
succeeds.
Expected behaviour
The backup archive generated by LuCI should be directly restorable using
the same LuCI interface without requiring manual recompression or
post-processing.
Steps to reproduce
- Open LuCI
- Navigate to System → Backup / Flash Firmware
- Click "Generate archive"
- Download the generated
.tarfile - Attempt to restore it via LuCI
