Robust E2E Fix: Ensure live URL is used for final site build

- Updated ci/test-e2e.sh to manually inject the live Onion URL into config.json.
- Re-runs voxvera build after URL generation to ensure QR codes reflect the live address.
- Fixes verification failure where the URL wasn't being correctly propagated in CI.
