PBI-46: Sprint-niveau jobflow met cascade-FAIL (F1/F2/F4 Scrum4Me) (#136)

* ST-1243: F1 schema + propagateStatusUpwards-helper voor sprint-flow

Schema-uitbreidingen voor de sprint-niveau jobflow (PBI-46):
- TaskStatus, StoryStatus, PbiStatus, SprintStatus krijgen FAILED
- Nieuwe enums: SprintRunStatus, PrStrategy
- Nieuw SprintRun-model dat per-task ClaudeJobs groepeert
- ClaudeJob.sprint_run_id koppeling + index
- Product.pr_strategy (default SPRINT)
- Bijhorende Prisma-migratie

propagateStatusUpwards vervangt updateTaskStatusWithStoryPromotion en
herevalueert de keten Task → Story → PBI → Sprint → SprintRun bij elke
task-statuswijziging. Bij FAILED cancelt het sibling-jobs in dezelfde
SprintRun. PBI-status BLOCKED blijft handmatig en wordt niet overschreven.

Status-mappers + theme krijgen failed-token + label-uitbreidingen.

* ST-1244: F2 sprint-runs actions + deprecate per-task enqueues

actions/sprint-runs.ts (nieuw):
- startSprintRunAction met pre-flight (impl_plan / open ClaudeQuestion / PBI BLOCKED|FAILED)
- Maakt SprintRun + ClaudeJobs in PBI→Story→Task volgorde
- resumeSprintAction zet FAILED tasks/stories/PBIs terug en start nieuwe SprintRun
- cancelSprintRunAction breekt lopende SprintRun af zonder cascade

actions/claude-jobs.ts:
- enqueueClaudeJobAction, enqueueAllTodoJobsAction, previewEnqueueAllAction,
  enqueueClaudeJobsBatchAction nu deprecation-stubs (UI-cleanup volgt in F4)
- cancelClaudeJobAction blijft beschikbaar voor losse jobs

Tests bijgewerkt: 11 nieuwe sprint-runs tests, claude-jobs(-batch) tests
herzien naar deprecation-asserties.

* ST-1246: F4 UI Start/Resume/Cancel sprint + pr_strategy dropdown

- components/sprint/sprint-run-controls.tsx: knoppen Start Sprint
  (sprintStatus=ACTIVE), Hervat sprint (sprintStatus=FAILED) en
  Annuleer sprint-run (lopende run). Pre-flight blocker-modal toont
  blockers met directe links naar de relevante pagina's.
- components/products/pr-strategy-select.tsx: dropdown SPRINT|STORY in
  product-settings, met optimistic update + sonner-toast op fail.
- actions/products.ts: updatePrStrategyAction (eigenaar-only, demo-block).
- Sprint-page: query op actieve SprintRun + tonen van controls-balk.

Live cascade-visualisatie (T-634) staat als follow-up genoteerd —
huidige sprint-board statusbadges volstaan voor MVP. De Solo-board
"Voer uit"-knoppen zijn niet expliciet verwijderd; ze tonen nu de
deprecation-error van de gestubde actions tot de Solo-flow opnieuw
ontworpen wordt.
