stealth(foundation): address review comments

- Always include core-ktx / lifecycle-livedata-ktx / work-runtime-ktx:
  these are used by the real app code (VPN status, logs, background work)
  in stealth builds too, not just regular builds.
- Drop the dangling proguard-stealth-novpn.pro reference; the existing
  proguard-rules.pro applies to all release variants (incl. stealth-novpn).
