Add finding and obligation publish to document system

Replace the old snapshot-based approach with the new publish document
system for findings and obligations. Includes GraphQL mutations, MCP
tools, CLI commands, e2e tests, frontend publish dialogs, and
snapshot-to-document migration tools.

Remove snapshot mode entirely from findings and obligations: drop
snapshotId from GraphQL schemas, filters, resolvers, MCP spec, frontend
routes, pages, and helpers. The snapshot_id column remains in the
database but is now filtered out with snapshot_id IS NULL.

Remove auditor's ability to publish SoA.
