The DocumentVersionSignatureFilter exposed a field named `state` that
actually filters on the signatory's profile state, which was ambiguous
next to the signature `states` field. Rename it to `profileState`
(GraphQL) / `profile_state` (MCP) across the schema, spec, resolvers,
console app, and n8n node for clarity.
