fix: break long shell chains into separate commands

The sed pipe | ssh 'cat >' pattern caused /bin/sh quoting errors
when all \ continued lines were combined into one -c argument.
Now each operation (sed, mv, scp) is an independent shell invocation.

fix: use tmpfile+scp instead of sed pipe to avoid shell quoting

The sed ... | ssh 'cat >' pattern caused /bin/sh quoting errors with
single quotes inside double-quoted sed expressions. Replaced with:
  sed ... > tmp && mv tmp FILE && scp FILE remote:

This avoids the pipe entirely and makes the shell command simpler.
