Subject: [PATCH] fix(canvas/test): remove unnecessary vi.restoreAllMocks from
 PurchaseSuccessModal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PurchaseSuccessModal.test.tsx never creates spies (no vi.spyOn, no
mockImplementation) so vi.restoreAllMocks() was a no-op in its
afterEach hooks. Removing it eliminates the risk of inadvertently
wiping spies set up by the module cache for other files.

Also reverts ApprovalBanner.test.tsx to its pre-PR-#480 state
(vi.useRealTimers() in afterEach, no mockReset calls) — the
PR-#480 change to vi.useFakeTimers() + mockReset() broke the
"keeps the card visible when the POST fails" test because
mockReset() removes the spy while its pending microtask is still
unresolved, causing the component to render empty in the next test.

Stable baseline: vi.useFakeTimers() in beforeEach,
vi.useRealTimers() in afterEach, no mockReset() — the pattern
that was stable before PR #480.
