v1.2.5

Changed

• Catalogue sync key is part of setup, no longer labelled optional: stores
  created in IDEA89 from 2026-10-01 do not sync without it.

Fixed

• A refused sync is reported, not swallowed. A 401 with
  sync_key_not_set, sync_key_required or invalid_sync_key on a
  catalogue write is stored in idea89_sync_key_rejection (not autoloaded,
  removed on uninstall) and shown on the settings page; the next accepted
  catalogue write clears it. sync_page ends the page chain on such a
  refusal and does not record idea89_last_full_sync_at.
• Test connection checks catalogue access. After /v1/catalog/stats it
  posts to /v1/catalog/verify with the sync key, and reports the API's
  message when catalogue writes would be refused. A 404 (an older API) still
  passes.
