Overview

This PR adds deterministic tests for the frontend InstallPrompt component, covering browser support detection, user rejection, and persisted dismissal behavior. It also makes the minimal component adjustments needed to expose those behaviors to the test suite.

Changes

🧪 Install Prompt Test Coverage

• [MODIFY] frontend/src/app/components/global_ui/InstallPrompt.tsx

  • Ensures the browser-support check, dismissal persistence, and rejection handling are observable and deterministic for tests (no behavior changes to the public prompt flow).

• [ADD] frontend/src/app/components/global_ui/__tests__/InstallPrompt.test.tsx

  • Covers the success path (prompt shown when the install event is available).
  • Covers the failure path (prompt not shown when the browser does not support installation).
  • Covers the boundary path (dismissal state respected across renders).
  • Covers the authorization/rejection path (user rejects the install prompt and dismissal is persisted).

Verification Results

npm test -- frontend/src/app/components/global_ui/__tests__/InstallPrompt.test.tsx
✅ Install prompt test suite passed

Acceptance Criteria	Status
Add deterministic tests for the success, failure, boundary, and authorization paths	✅ Covered in InstallPrompt.test.tsx
Run the tests in CI and assert the documented public behavior and error contract	✅ Tests exercise the component's public behavior and dismissal contract

Closes #2135
