fix(ft8): remove application tag from module manifest (merge conflict)

feature/ft8 module manifest carried an application element from the
FT8CN standalone app (allowBackup/icon/label/usesCleartextTraffic),
clashing with the main app manifest at merge (allowBackup false vs
true, icon, label). Removed the tag - components (activities, service,
permissions) remain and merge cleanly. Verified: processRelease-
MainManifest + mergeReleaseResources BUILD SUCCESSFUL.
