[Testing] Zero test coverage for `SubmitProofScreen` — the core proof submission flow

[cybermax4200]

Why this matters now: SubmitProofScreen.tsx is the most complex screen in the app: it manages camera permissions, photo capture, GPS location, proof submission, activity creation, impact stat updates, proof status polling, and notification scheduling. It has 364 lines of business logic with zero tests. A regression here silently breaks the core value loop: task → proof → reward.

Problem / What: src/screens/SubmitProofScreen.tsx (364 lines) — no test file. The screen orchestrates useCameraPermission, useLocation, useProofSubmit, useProofStatus, useActivityStore, useUserStore, and scheduleLocalNotification.

Key Challenges:

• Mock react-native-vision-camera: useCameraPermission, useCameraDevice, Camera.
• Mock useLocation, useProofSubmit, useProofStatus.
• Mock useActivityStore, useUserStore.
• Mock scheduleLocalNotification.
• Test: photo capture flow (permission → capture → preview).
• Test: successful submission → activity created → stats updated → notification fired.
• Test: offline submission → activity queued → error displayed.
• Test: retake photo resets state correctly.
• Test: no task ID shows EmptyState.
• Test: location error display.

Acceptance Criteria:

• Test file src/__tests__/SubmitProofScreen.test.tsx with 12+ test cases.
• Camera capture flow.
• Successful proof submission with activity and stat updates.
• Offline/queued submission.
• Retake photo state reset.
• Empty state when no taskId.
• All tests pass with npm test.

Relevant files/functions:

• src/screens/SubmitProofScreen.tsx (entire file)
• src/__tests__/SubmitProofScreen.test.tsx (new)

Out of scope: Real camera integration, IPFS pinning.

gm gm boss, I’d like to take this on. I’ll add comprehensive coverage for SubmitProofScreen, mocking the camera, location, submission/status hooks, stores, and notifications, with 12+ focused cases covering capture, submission, offline queuing, retakes, missing task IDs, and location errors. I’ll verify everything with npm test while keeping real camera/IPFS integration out of scope.
