feat(worker-logs): add worker run-log viewer page

Nieuwe /worker-logs pagina: een tabel van de laatste N (10/25/50/100)
worker-runs met een inline detailpaneel dat de stream-json output van
Claude Code als leesbare timeline toont (system-init, assistant-tekst,
tool-calls/results, result-kaart).

- lib/parse-worker-log.ts: pure parser — summarizeRunLog (tabel) +
  parseRunLog (timeline), discriminated-union events, server-side
  truncatie van grote tool-results.
- lib/worker-logs.ts: server-only fs-toegang, leest uit WORKER_LOGS_DIR
  (read-only bind mount), naam-regex + pad-confinement, .gz support.
- app/api/worker-logs[/[name]]: GET-routes, auth-guarded, force-dynamic.
- app/worker-logs: server page + client view (tabel, N-selector,
  auto-refresh) + detail (timeline, auto-refresh tijdens in-progress run).

Vereist een read-only bind mount van /srv/scrum4me/worker-logs in de
ops-dashboard-container (docker-compose.yml + WORKER_LOGS_DIR in .env).
