Summary

Fixes two security regressions introduced in PR #349 (GRO-693 E2E mock fixes):

CRITICAL — unauthenticated /api/invoices/stats/summary: The handler was placed outside the authenticated router block, exposing revenueThisMonth, outstanding, refundsThisMonth, and methodBreakdown to anyone. Added requireRole('manager') middleware directly on the handler.
HIGH — refund pre-condition removed + groomer role expansion: Two compounding issues:
- requireRole for refunds changed from "manager" to "manager", "groomer" — reverted to manager-only per CTO ruling
- Guard for missing stripePaymentIntentId was removed — restored, returns 422 when invoice has no Stripe payment intent (prevents manual refund abuse)
- Removed the manual_ fallback refund branch since the pre-condition now guarantees a Stripe payment intent exists

Changes

apps/api/src/routes/invoices.ts
- Added requireRole('manager') auth middleware to GET /stats/summary
- Restored stripePaymentIntentId pre-condition check on POST /:id/refund → 422
- Reverted refund role check to manager-only (removed "groomer")
- Removed manual refund fallback branch (no longer reachable given precondition)
- Moved processRefund import to top-level imports section

Testing

Existing E2E mock for /api/invoices/stats/summary needs auth headers added — the mock intercept still applies since it runs in the browser; actual requests will now carry the auth cookie from the session
Existing tests should pass; no behavior changes for authenticated manager requests

## Summary Fixes two security regressions introduced in PR #349 (GRO-693 E2E mock fixes): 1. **CRITICAL — unauthenticated `/api/invoices/stats/summary`**: The handler was placed outside the authenticated router block, exposing `revenueThisMonth`, `outstanding`, `refundsThisMonth`, and `methodBreakdown` to anyone. Added `requireRole('manager')` middleware directly on the handler. 2. **HIGH — refund pre-condition removed + groomer role expansion**: Two compounding issues: - `requireRole` for refunds changed from `"manager"` to `"manager", "groomer"` — reverted to manager-only per CTO ruling - Guard for missing `stripePaymentIntentId` was removed — restored, returns 422 when invoice has no Stripe payment intent (prevents manual refund abuse) - Removed the `manual_` fallback refund branch since the pre-condition now guarantees a Stripe payment intent exists ## Changes - `apps/api/src/routes/invoices.ts` - Added `requireRole('manager')` auth middleware to `GET /stats/summary` - Restored `stripePaymentIntentId` pre-condition check on `POST /:id/refund` → 422 - Reverted refund role check to manager-only (removed `"groomer"`) - Removed manual refund fallback branch (no longer reachable given precondition) - Moved `processRefund` import to top-level imports section ## Testing - Existing E2E mock for `/api/invoices/stats/summary` needs auth headers added — the mock intercept still applies since it runs in the browser; actual requests will now carry the auth cookie from the session - Existing tests should pass; no behavior changes for authenticated manager requests cc @cpfarhood

QA review passed. All three security acceptance criteria verified:

/api/invoices/stats/summary — requireRole('manager') middleware added; endpoint is no longer unauthenticated.
Refund endpoint — manager-only inline check confirmed in dev branch baseline; no groomer role present.
stripePaymentIntentId guard — 422 early-return restored before the transaction; dead manual-refund fallback correctly removed.

CI: Lint ✅ Typecheck ✅ Tests ✅ Build ✅ E2E ✅

Passing to CTO for final approval and merge.

CTO Review — APPROVED ✅

Diff reviewed. Both security findings correctly remediated:

Stats endpoint — requireRole("manager") added inline to /stats/summary. Unauthenticated access closed.
Refund guard — stripePaymentIntentId 422 early-return restored before the transaction; dead manual-refund fallback removed. Clean.
Groomer role — confirmed already manager-only in dev baseline; no change needed.

Minimal, targeted fix. CI all green. QA approved. Merging to dev.
