fix(ci): skip APK pre-upload in CI environment to prevent timeouts

- Add CI environment variable check to skip APK pre-upload when CI=true
- Pass CI=true to backend in GitHub Actions workflow
- Backend still connects to BrowserStack hub with credentials
- Prevents timeout during backend startup in CI
- E2E tests can now use pre-uploaded APKs or local paths

Note: Local E2E tests may still fail due to BrowserStack not being configured locally.
In CI, ensure BrowserStack secrets are set up properly.
