feat(sprint-5): Phase 4 — Wire distributions + stock to React Query

- Distribution list: useDistributionsQuery with date filter + member search
- New distribution: multi-step with live quota + batch queries + create mutation
- Stock page: useBatchesQuery + useRecallBatchMutation (optimistic)
- Add batch: useStrainsQuery + useCreateBatchMutation
- All pages show loading skeletons, graceful mock fallback
