alexsong-oai cc2f80d515 Add file-backed storage for gateway OAuth credentials (#58219) ...

## What changed

Allow gateway OAuth configuration to select `credentials_store = "file"` to persist credentials in plaintext at `$CODEX_HOME/secrets/gateway_oauth.json`. Keep `keyring` as the default.

Read, update, and delete file-backed credentials by credential ID, using atomic writes and the existing cross-process lock. Preserve the serialized provider identity when using the default store.

## Testing

Add an app-server test that completes gateway OAuth login with file storage, verifies Unix file permissions are `0600`, and checks that login remains successful after a server restart.
