closes board-viewer-card-meta-fix
Review found two acceptance fields missing from cards:
- project_owner was in JSON but never displayed
- last_commit_iso was only consumed for relative age; no absolute date
Now both rendered (server-side src/render.ts + client-side static/board.js
in sync), with 4 new TDD tests:
- renders owner pill when project_owner is set
- omits owner pill when empty
- renders short YYYY-MM-DD date when last_commit_iso is set
- omits date span when null
CSS: .badge.owner = transparent + border (visually distinct from solid
.badge.project), .date = small muted tabular-nums. Smoke-verified in browser.
