deleteJetpack
Hard-deletes the document identified by the model's userId and id.
The repository uses this for pending local soft deletes, then acknowledges the retained local row. No remote tombstone is written, so incremental pulls cannot remove another device's existing row.
Parameters
firebaseJetpack
Identifies the owner and document; other fields are not used.
Throws
com.google.firebase.firestore.FirebaseFirestoreException
if the SDK delete fails
