Add Quick Lead workflow integration tests (#16862)

## Description

This PR adds integration tests for the Quick Lead workflow, including a
complete end-to-end test with full workflow execution.

### Key Changes

1. **Enabled SyncDriver for integration tests** - Jobs are now processed
synchronously in tests
   - Modified `create-app.ts` to use `SyncDriver` instead of `BullMQ`
- Added `MessageQueueExplorer` to discover and register workflow job
handlers
   - This enables complete workflow execution in integration tests

2. **Added integration tests for Quick Lead workflow**:
   - Verify workflow exists and is active
- Verify workflow version has correct structure (MANUAL trigger, FORM
step, CREATE_RECORD steps)
- Test workflow triggering creates workflow run with correct initial
state
   - Test stop workflow run on a running workflow
- **Full end-to-end test**: trigger → submit form → verify Company and
Person records created

### Test Coverage

The complete end-to-end test verifies:
- Workflow triggers and is in RUNNING status (waiting on FORM step)
- Form submission with test data succeeds
- Workflow completes successfully with all steps in SUCCESS status
- Company record is created with correct name and domain
- Person record is created with correct name and email
- Records are properly cleaned up after test

### How to Run Tests

```bash
npx nx run twenty-server:test:integration -- --testPathPattern="quick-lead-workflow"
```

Or with database reset:

```bash
npx nx run twenty-server:test:integration:with-db-reset -- --testPathPattern="quick-lead-workflow"
```
