app.tempomusic.staff.createInviteCode

Generate a batch of single-use PDS invite codes (TEM-502). Requires the caller to have the `superAdmin` role. Each call requests `quantity` codes from the PDS (`com.atproto.server.createInviteCode` with `useCount=1`), writes one `inviteCodeCreated` audit row per successfully-created code (payload = SHA-256 hash of the suffix + `use_count`, never the plain code), and returns the suffix-only codes. When the PDS returns a transient failure mid-batch the handler stops iterating and returns the successfully-generated codes together with the requested count (partial-batch surfacing — the client decides whether to retry the missing count).
