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.
