The optimistic package_data entry painted at install-spawn survived
failure as a 'Stopped' tile for an app with zero footprint (netbird on
the fresh ISO). On INSTALL FAIL with no container/user-stop marker for
the app, the entry and the pre-saved dynamic app config are removed and
an error notification is pushed; failures that left a real container
keep today's behavior (visible exited state for retry/diagnosis).
Install suite 39/39.
