Audit Log view: surface the new entity name column (nextjs-app-layer follow-up)

[herbie-bot]

Context

Spec 106 (#33, spring-services 0.16 upgrade) added the name field to AuditLogEntity/AuditLogDto and now returns it in GET /api/audit-logs. The backend work is complete.

The admin Audit Log view that renders this data lives in the published @open-elements/nextjs-app-layer package (.../audit-logs-client.tsx), not in this repo, so the frontend column was intentionally deferred (see spec 106 Non-goals).

Goal

Once a @open-elements/nextjs-app-layer release exposes it, add a Name column to the admin Audit Log table between the existing entity-id and action columns, matching the name field now present in the /api/audit-logs JSON.

Acceptance criteria

• Audit Log admin table shows the name value for each row
• Historical rows (backfilled "UNKNOWN") render without error
• Column placement matches the DTO order (between entity id and action)

Follow-up to #33 / spec 106-spring-services-0.16-upgrade.
