test(platform-objects): the metadata-form catalog's per-locale positive control reads 659 once the agent lifecycle row leaves

The agent form's `lifecycle` row left with the retired key, and with it a row

echo-decisions pin counted it (660); it now reads 659, with the reason recorded
beside the history of the count.
