feat(dashboard): entity list UX — REF column, name cells, detail pages (CUST-WP-0030)
- ref-cell.js: REF column component — click=copy deeplink, dblclick=open
- field-help.js: field registry + fieldRow helper with help-tip decoration;
FK fields (task_id, workstream_id, repo_id) render as async-linked cells
with entity-title bubble-help on hover
- GET /token-events/{id} endpoint + get-by-id tests
- GET /repos/by-id/{repo_id} UUID lookup endpoint
- Landing pages: /token-events/[id], /workstreams/[id], /repos/[slug], /tasks/[id]
- token-cost.md: REF + Name columns on all three tables; parallel fetch of
workstreams/tasks for title resolution
- reference.md: entity detail page URL scheme documented
