fix(FR-2901): sync deployment revision state in Relay store after activate / auto-activate

Mutations that change deployment.currentRevisionId/deployingRevisionId
left the Relay store stale, so the row tags in the revision history
table and the Configuration Section's current/deploying indicators
could drift apart from the server.

- activateDeploymentRevision: extend the mutation response to include
  deployingRevisionId and the full DeploymentRevisionDetail_revision
  fragment on both currentRevision and deployingRevision, so the
  normalized deployment record updates atomically.
- addModelRevision (autoActivate=true): AddRevisionPayload does not
  expose deployment yet, so fire a best-effort fetchQuery on the same
  fields the detail page reads after the mutation completes. The
  parent's onRequestClose(true) callback still triggers fetchKey as a
  safety net. A code comment documents the temporary nature so the
  fetch can be removed once AddRevisionPayload.deployment lands.
