rob 6bb0b19f45 Harden restore-volumes.sh against silent restore truncation and incomplete-download skips ...

- BUG 1: Add error checking after tar extraction for both LOCAL and REMOTE-CACHE branches
  - Check exit status of tar -I zstd -xf commands
  - Print error to stderr and exit non-zero on failure
  - Prevents silent truncation where corrupt/incomplete backup extracts partial data
  - Mirrors existing remote-STREAM branch error handling
- BUG 2: Fix REMOTE branch to resume incomplete aria2c downloads
  - Check for presence of <file>.aria2 control file as incomplete signal
  - aria2c -c continues/resumes download when .aria2 file exists
  - Only skip download when file exists AND no .aria2 control file remains
  - aria2 deletes .aria2 sidecar on successful completion, making it a reliable signal
- Maintain all existing flags: aria2c -c -Z -x8 -j8 -s8 -d
- Preserve reth guard logic and static-file offload behavior unchanged
