feat: add e2e test user seeding for CI

Created seeds_e2e.exs to automatically create a test user with TOTP enabled
for Playwright e2e tests. This ensures tests can authenticate in CI without
requiring manual user setup.

Test credentials (for CI only):
- Email: test@example.com
- Password: TestPassword123!
- TOTP Secret: JBSWY3DPEHPK3PXP (fixed for reproducibility)

The workflow now:
1. Loads database structure
2. Seeds test user with TOTP
3. Passes credentials to e2e tests via environment variables
