Assets as document: replace snapshot with publish workflow

Remove assets from the snapshot system and replace with a publish-based
document workflow that generates versioned ProseMirror documents.

- Remove snapshot_id/source_id from asset and asset_vendor models
- Delete AssetFilter (no longer needed without snapshot filtering)
- Add PublishAssetList service, GraphQL mutation, MCP tool, CLI command,
  and n8n operation
- Add asset_list_document_id column to generated_documents table
- Generate ProseMirror documents with asset inventory tables
  (name, type, amount, data types stored, owner, vendors)
- Add AssetListDocument resolver on Organization type
- Update frontend to remove snapshot routes/params and add publish dialog
- Add e2e tests for asset publish (immediate, with approvers, reuse, RBAC)
- Add migration script for converting legacy asset snapshots to documents
- Exclude ASSETS from snapshot type lists and e2e snapshot tests
- Move generated_documents SQL to coredata methods on Datum and Asset
- Clear generated document and SOA references on soft delete and archive
