feat(flows): redeploy_all flow + fix MCP-worker cache-bust

Legt de volledige stack-redeploy vast als één flow: scrum4me-web
(pull/migrate/build/restart) gevolgd door de MCP-worker.

Onderweg een echte bug gevonden en gefixt: update_mcp_worker.yml deed
`docker_compose_build worker-idea` zónder cache-bust. De worker-idea
Dockerfile clonet scrum4me-mcp van GitHub in een aparte laag; zolang
MCP_GIT_REF gelijk blijft ('main') hergebruikt Docker die laag, dus
nieuwe MCP-commits werden NIET opgepikt. Een schijnbaar geslaagde
rebuild draaide stilletjes op oude MCP-code.

Wijzigingen:
- commands.yml.example: nieuw command docker_compose_build_worker_fresh
  dat via `sh -c` MCP_CACHE_BUST=$(date +%s) meegeeft — invalideert de
  clone-laag zodat de laatste MCP-code wordt gepulld
- update_mcp_worker.yml: gebruikt nu de fresh-build; pullt ook
  scrum4me-mcp lokaal (on_failure: continue, sync-only)
- redeploy_all.yml: nieuwe gecombineerde flow (16 stappen, web → worker)
- app/flows/redeploy-all/: UI-pagina + panel, zelfde patroon als de
  bestaande flow-pagina's
- app/flows/page.tsx: Redeploy All bovenaan de flows-lijst
