An image-pull failure (e.g. the MTU-EOF black hole) left apps marked
installed+active with no container: the compose `up -d` failure was invisible
because (a) checkSuccess read $? after `_rc=$?`, always printing "✓ Started",
and (b) the exit code is dropped across dockerComposeUpdateAndStartApp →
dockerComposeUpdate → dockerComposeRestartAfterUpdate, and installApp never
checked it — so post-install integrations ran and set status=1 regardless.
- up_app.sh: restore $? to the compose exit before checkSuccess (both rootless
and rooted) so a failed `up -d` is reported as an error + logged, not "✓".
- app_install.sh: after `up`, reality-gate on the app's compose project having
at least one container (ps -a, so a slow-to-start container still counts).
If none exists, print a clear failure, skip _appPostStartIntegrations (which
is what records the app + sets status=1), and return non-zero.
Verified: the gate query passes for a running app (libreportal) and refuses
apps with no container (navidrome/ipinfo after their pulls EOF'd).
