M12e: contract pass (pair invite kind, admin name in invite links, sync failed flag, rejection actor, device version name, template id, update check result, untouched accounts, D-027 re-stamp, PushEvent in :core:model, snackbar hosts)

Server: E-3 invite_kind; E-12 link ?from=<admin name>, E-4 passes it into kvitt://invite;
X-Kvitt-App-Version-Name stored in devices.app_version_name (migration 0003, schema 3);
OpenAPI and examples follow. Phone: :core:model, :core:fakes, :data, features and :app
updated together; goldens re-recorded for S-20 (version name) and new S-1/S-22 states.
