Description

## Description

3 out of 5 GDPR E2E tests are failing due to admin login timeouts that occur after a test user logs out. The tests have been temporarily skipped with `test.describe.skip` to unblock Phase 12 completion.

## Affected Tests

Located in `frontend/tests/e2e/Gdpr.spec.ts`:

1. **Mixed Scenario: User Creates Data, Admin Exports** (line 180)
   - User registers, logs in, creates activity, logs out
   - Admin tries to log in → **TIMEOUT** waiting for navigation

2. **Audit Logs Verification** (line 251)
   - User exports data, logs out
   - Admin logs in and checks audit logs → **ERR_ABORTED on /login**

3. **Cross-Organization Access** (line 305)
   - Create 2 test users
   - Admin logs in to verify cross-org access → **TIMEOUT** on navigation

## Root Cause (Hypothesis)

Browser state (localStorage/cookies) is not being properly cleared between user logout and admin login within the same test. This might cause:
- Stale auth tokens interfering with new login
- Race condition in `authStore.init()`
- Session cookie conflicts

## Working Tests (for comparison)

These 2 tests pass successfully:

1. **Complete User Journey** ✅
   - User registers, logs in via UI, exports, erases account
   - No admin login involved

2. **Admin Operations** ✅
   - User registers via API (never logs in via UI)
   - Admin logs in fresh without prior user session
   - Successfully exports and erases user data

## Error Examples

### Timeout Error
```
Error: page.waitForURL: Timeout 10000ms exceeded.
=========================== logs ===========================
waiting for navigation to "/admin" to be finished
============================================================
```

### ERR_ABORTED
```
GET http://localhost:3000/login net::ERR_ABORTED
```

## Investigation Steps

1. Add explicit `page.context().clearCookies()` after user logout
2. Add `localStorage.clear()` via `page.evaluate()`
3. Check if `authStore.logout()` properly clears all state
4. Consider using separate browser contexts for user vs admin sessions
5. Add debug logging to track token state transitions

## Test Status

- ✅ 2/5 passing (40%)
- ⏭️ 3/5 skipped (timeout issues)

## Priority

Medium - Tests are temporarily skipped, but should be fixed before production deployment.
