Add document webhook events

Add a resource-oriented set of webhook events for the document
lifecycle. Each event carries the document plus only the sub-resource
it concerns (version, signature or approval).

Events:
- document.created / updated / archived / unarchived / deleted
- document.version.created / updated / published / rejected / deleted
- document.version.signature.requested / signed / cancelled
- document.version.approval.requested / approved / rejected / voided

Wires the new types through the migration, Go enum, GraphQL schema,
CLI, n8n nodes and the console webhooks settings UI.
