"""Create entity_attachments table — references DMS files.
Instead of storing files in a separate attachment storage path,
all files go through the DMS (files table) and entity_attachments
just references the DMS file with entity_type/entity_id.
This unifies the storage layer: one upload path, one download path,
one permission model, one deduplication (content_hash).
Revision ID: 0071
