Pull request overview

Fixes a race/invalid-state path where an app could still be installed even after its selected version was removed remotely, by ensuring the UI cannot submit without a valid appDetailId and by returning a dedicated backend error when remote compose content is missing (404).

Changes:

• Frontend: disable/guard install submission until a valid appDetailId is loaded for the selected version.
• Frontend: reset install form state when switching versions and ignore stale getAppDetail responses.
• Agent: propagate non-200 HTTP status codes from request helper and map 404s to ErrAppVersionUnavailable with translations.
