feat(documents): entity-aggregated query params + signing-details API

GET /api/v1/files?entityType=client&entityId=… and the same params on
the documents route return the owner-aggregated projection
{ groups: [{ label, source, files|workflows, total }] }. folderId
remains for direct-folder listing; the two modes are mutually
exclusive (zod refine).

GET /api/v1/documents/[id]/signing-details returns
{ workflow, signers, events } for the "view signing details" dialog
on signed-PDF rows.
