fix(uninstall): always run name-based container cleanup + drop CLI hint

Two small uninstall-output tweaks.

1. dockerComposeDownRemove now ALWAYS calls dockerRemoveApp (the
   `docker ps -aqf name=…` → stop + rm sweep) as a fallback, even when
   the compose-down step is skipped because the app dir is missing.
   Before, a partial prior uninstall (compose file gone but containers
   still running) produced "App directory not found. Skipping container
   shutdown." and then proceeded as if the uninstall were complete —
   leaving the actual containers running. The name-based sweep also
   runs after a successful compose-down to catch anything compose
   wouldn't pick up (renamed services, orphans from earlier failures).

   While here: the OS_TYPE gate (only Ubuntu/Debian) is gone too —
   `docker compose down` works on any OS with docker, and gating it
   meant Arch/etc. users got NO compose teardown at all.

2. The step-2 header "Keeping Docker images (pass --delete-images to
   remove)" trimmed to just "Keeping Docker images". The `isNotice`
   line below already explains the reuse-on-reinstall behaviour; the
   CLI-flag hint reads as noise in the WebUI task log where users
   can't act on it anyway. CLI users can still pass --delete-images
   (cli_app_commands.sh wires it as before) or tick the WebUI's
   "Also delete docker image" checkbox.
