Add an env-driven `user:`/`group_add` to the filestash service plus
tooling/filestash-set-run-user.sh. Running the container as a real host
account (oxps: oier=1002) makes every file it writes into the share owned
by that account, so scp/ssh and the web UI share one owner — no chown dance.
Defaults FILES_UID/FILES_GID=1000, leaving cochi (image's own uid) untouched.
group_add 1000 keeps the 0730 image binary + 0770 /app/data usable under any
uid; the helper also chowns the filestash_state volume (1000:1000) so a
non-1000 uid doesn't crash-loop unable to write its own sqlite/config.
