feat(ui): TDS migration stage 2 — six page views and page modules

- Dashboard, Workers, Workflows, Executions, Quick Command, Scheduler pages on the
  shared layout, all behaviour via Pulse delegated actions (no inline handlers)
- Executions: server-driven Manual/Automated views, compare mode, detail modal with all
  log types, ?open= deep link, cross-page re-run via sessionStorage
- Workflows: run modal (dry-run available for every workflow), create modal pre-filled
  with the example definition
- Fix EJS comment in page-header partial that broke rendering
