fix(e2e): set MCPMUX_E2E_TEST=1 in wdio.conf.ts for consent endpoint

The previous commit gated /oauth/consent/approve behind the
MCPMUX_E2E_TEST env var but the e2e test runner was not passing
it to the tauri-driver process. This caused streamable-http tests
to fail because obtainAccessToken() and approveOAuthClient() both
depend on test-only endpoints.
