Update Claude on container start; harden file-list scroll

Add a time-bounded `claude update` to entrypoint.sh that runs as the
claude user before the container is marked ready, so every terminal
session launches the latest CLI. Non-fatal and capped at 120s so an
offline/slow network never blocks container readiness; PATH covers both
~/.claude/bin and ~/.local/bin install locations.

Add flex-shrink-0 to the FileManagerModal header/footer so a long file
list can't squeeze them and the scroll region stays robust.
