feat(rate-limit): per-user mutation-rate-limiting (v1-readiness #3)

lib/rate-limit.ts: 11 nieuwe scope-configs + enforceUserRateLimit(scope, userId)
helper. Returnt { error, code: 429 } shape voor consistent foutbeleid.

Toegepast op de high-value mutation-paths:
- actions/pbis.ts createPbiAction
- actions/stories.ts createStoryAction
- actions/tasks.ts saveTask (alleen create-path) + createTaskAction
- actions/todos.ts createTodoAction
- actions/sprints.ts createSprintAction
- actions/products.ts createProductAction + createProductFormAction
- actions/api-tokens.ts createApiTokenAction
- actions/questions.ts answerQuestion
- actions/claude-jobs.ts enqueueClaudeJobAction + enqueueClaudeJobsBatchAction
- app/api/profile/avatar/route.ts POST
- app/api/stories/[id]/log/route.ts POST

Limits zijn ruim genoeg voor normaal gebruik, eng genoeg voor abuse-loops:
create-task 100/min, create-todo 60/min, create-pbi 30/min, create-product
5/min, create-token 10/uur, etc. Per-user scope (geen globale block).

Niet aangeraakt: reorder/status-toggle (intra-session frequent, lage abuse),
update/delete (laag-volume), cron-routes (CRON_SECRET-gated).

Consumer-tweaks: 'success' in result narrowing waar TS de bredere union niet
meer accepteerde. Tests: 9 nieuwe op rate-limit-helper.
