Allow editing metadata of generated document versions

Title, document type, and classification on generated documents could
not be changed: any version-tracked field on a GENERATED write-mode
document was rejected with ErrDocumentVersionGenerated. The error now
fires only when content is being changed, so manual metadata edits
flow through the same draft-on-edit path as authored documents and
produce a draft version that the user can review and publish.

The CLI document update --document-type enum gains
STATEMENT_OF_APPLICABILITY (which generated SoA documents already
use), and the GraphQL resolver maps the content-edit rejection to a
Conflict instead of falling through to a generic Internal error.
