"""In-container patch: add scopeKey + revisionId to the served OTA manifest.

The Android expo-manifests SDK requires:
  ExpoUpdatesManifest.getScopeKey()  -> extra.scopeKey  (must be present)
  Manifest.getRevisionId()            -> expoClient.revisionId (must be present)
Both are currently MISSING from the served manifest => UpdateFailedToLoad at
UpdateFactory.kt:19. This patch adds them. Reversibility: a .bak of the
original file is taken before editing (already exists from a prior cp), and
this writes a fresh timestamped .bak too.
