<objective>
Fix act() warnings in BackendSelectionStep.test.tsx by migrating from fireEvent to userEvent v14, and suppress ReviewStep act() warnings with vi.useFakeTimers() for the OutputBlock setTimeout.

Purpose: TECH-05 — clean test output with zero act() warnings makes CI signal trustworthy and prevents false positives.
Output: Both test files use act()-safe patterns; no production code changes.

<!-- Key patterns — extracted from RESEARCH.md -->

userEvent v14 API (already installed: @testing-library/user-event 14.6.1):
```typescript
import userEvent from '@testing-library/user-event';

// Per test or per describe block
const user = userEvent.setup();
// ...
await user.click(element);    // replaces fireEvent.click(element)
await user.type(input, text); // replaces fireEvent.change(input, { target: { value: text } })
```

The user setup() instance must be created INSIDE describe() or it() (not at module level) to avoid state leakage between tests.

BackendSelectionStep.test.tsx — which fireEvent calls to migrate:
- fireEvent.change(nameInput, { target: { value: '...' } }) → await user.type(nameInput, '...')
  NOTE: user.type() appends to existing value. If input has a defaultValue, use user.clear() first or set up user.type with full value.
  Alternative: fireEvent.change is safe for setting values (no state updates) — only fireEvent.click triggers async state. Can keep fireEvent.change and only replace fireEvent.click.
- fireEvent.click(azureButton) → await user.click(azureButton)
- All it() callbacks that contain await user.click() MUST be async

vi.useFakeTimers pattern for ReviewStep (for OutputBlock's setCopied setTimeout):
```typescript
import { beforeEach, afterEach, vi } from 'vitest';

beforeEach(() => {
  vi.useFakeTimers();
  // Note: existing beforeEach in ReviewStep.test.tsx runs vi.clearAllMocks() and sets up stubs
  // Add vi.useFakeTimers() call to the EXISTING beforeEach block (not a new one)
});

afterEach(() => {
  vi.useRealTimers();
});
```

Root cause reference:
- BackendSelectionStep: fireEvent.click on a backend card → handleSubmit → async React Hook Form validation → dispatch → WizardProvider state update — all without act() wrapping
- ReviewStep: fireEvent.click on Copy button → setCopied(true) → setTimeout(() => setCopied(false), 2000) — timer fires after test assertion, producing act() warning from OutputBlock

<task type="auto" tdd="true">
  <name>Task 1: Migrate BackendSelectionStep.test.tsx from fireEvent to userEvent</name>
  <files>src/components/wizard/BackendSelectionStep.test.tsx</files>
  <behavior>
    - All WIZD-01 and WIZD-04 tests continue to pass (same assertions, just act()-safe interactions)
    - Vitest output for BackendSelectionStep.test.tsx contains zero occurrences of "act(" in warnings
    - Tests that previously used await waitFor() still use it (async validation is still async)
    - Tests that clicked backend cards use await user.click() and are async
  </behavior>
  <action>
    Edit src/components/wizard/BackendSelectionStep.test.tsx:

    1. Remove fireEvent from the @testing-library/react import (keep render, screen, waitFor)
    2. Add import: `import userEvent from '@testing-library/user-event';`
    3. For each it() that calls fireEvent.click on a backend card button, convert to userEvent pattern:
       - Add `const user = userEvent.setup();` at the top of the it() body
       - Make the it() callback async
       - Replace `fireEvent.click(azureButton)` with `await user.click(azureButton)`
       - Replace `fireEvent.change(nameInput, { target: { value: 'my-remote' } })` with `await user.clear(nameInput); await user.type(nameInput, 'my-remote');`
         OR keep fireEvent.change for input value setting and only replace fireEvent.click (fireEvent.change does not trigger act()-needing state updates in this component — either approach is valid)

    Specific tests to migrate (all 5 tests in BackendSelectionStep.test.tsx that use fireEvent):
    - WIZD-01: 'clicking a backend card dispatches SET_BACKEND_TYPE and SET_STEP'
    - WIZD-04: 'shows inline error after first Next attempt with invalid name'
    - WIZD-04: 'accepts alphanumeric, dashes, and underscores'
    - WIZD-04: 'rejects names with spaces or special characters'
    - WIZD-04: 'renders remote name input at the top of the step' (if it uses fireEvent — check)

    Tests that only use screen queries and no interactions (e.g., 'renders Azure Blob Storage card') do NOT need changes.

    Anti-patterns to avoid:
    - Do NOT wrap fireEvent.click in act() manually — replace with userEvent instead
    - Do NOT use legacy `userEvent.click()` shorthand — always use `userEvent.setup()` + `await user.click()`
    - userEvent.setup() must be inside the test body, not at module level

    After changes, verify no fireEvent.click calls remain in the file.

    All BackendSelectionStep tests pass.

  <name>Task 2: Fix ReviewStep act() warnings with vi.useFakeTimers</name>
  <files>src/components/wizard/ReviewStep.test.tsx</files>
  <action>
    Edit src/components/wizard/ReviewStep.test.tsx:

    1. Add `afterEach` to the existing imports from vitest: `import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';`

    2. Add `vi.useFakeTimers()` at the start of the existing `beforeEach` block (before vi.clearAllMocks()):
       ```typescript
       beforeEach(() => {
         vi.useFakeTimers();  // ADD THIS LINE FIRST
         vi.clearAllMocks();
         vi.mocked(downloadZip).mockResolvedValue(undefined);
         vi.stubGlobal('navigator', { clipboard: { writeText: vi.fn().mockResolvedValue(undefined) } });
         vi.stubGlobal('URL', { createObjectURL: vi.fn(() => 'blob:mock'), revokeObjectURL: vi.fn() });
       });
       ```

    3. Add a new `afterEach` block after beforeEach:
       ```typescript
       afterEach(() => {
         vi.useRealTimers();
       });
       ```

    This suppresses the act() warning from OutputBlock's `setTimeout(() => setCopied(false), 2000)` — the timer is frozen during tests and never fires unexpectedly.

    No other changes needed — all existing assertions remain valid with fake timers active.
    The new TECH-01 and TECH-02 tests from Plan 00 also benefit from this change (no warnings from their interactions either).

  <verify>
    <automated>cd /c/Users/SebastienQUEROL/Documents/projets/Ready2Blob && npx vitest run src/components/wizard/ReviewStep.test.tsx 2>&1 | grep -E "act\(|Tests" | head -10</automated>
  </verify>
  <done>
    All ReviewStep tests pass (including TECH-01 and TECH-02 new cases from Plan 00).
    Zero lines containing "act(" appear in the test output.
  </done>
</task>

Full suite must be entirely green with zero act() warnings:
```
cd /c/Users/SebastienQUEROL/Documents/projets/Ready2Blob && npx vitest run 2>&1 | grep -E "act\(|Test Files|Tests"
```
Expected:
- "Tests X passed (X)" with no failures
- Zero lines containing "act("
- npx tsc --noEmit: zero errors
</verification>

<success_criteria>
- BackendSelectionStep.test.tsx uses userEvent.setup() + await user.click() for all card interactions
- ReviewStep.test.tsx uses vi.useFakeTimers() in beforeEach and vi.useRealTimers() in afterEach
- Full Vitest run produces zero "act(" warning lines
- All 5 requirements (TECH-01 through TECH-05) verified green in the full test suite
- npx tsc --noEmit: zero errors (phase gate)
</success_criteria>
