API-key, widget and public-link callers were held to the write allowlist
only on connected accounts, so they could still write through an API
tool or a signed-in MCP server that carries the owner's credentials. Any
write on credentials the caller doesn't hold is now refused unless the
owner allowlisted it, and a scheduled run for such a caller counts as not
holding any. The tool list names these writes per tool, so the allowlist
can offer them, and its copy now names every route it covers.
