Register Anthropic access-review connector

Add the ANTHROPIC connector_provider enum value, its migration, and the
GraphQL enum binding, then register the provider as an API-key connector
that authenticates via x-api-key.

The probe URL is left empty because the shared connection probe cannot
send the required anthropic-version header and would misreport a valid
key; a dead key surfaces on the first member fetch instead.
