chore: bump version to 18.0.0-rc.2

- Bump @ngx-translate/core to 18.0.0-rc.2
- Bump @ngx-translate/http-loader to 18.0.0-rc.2
- Update http-loader peer dep to "@ngx-translate/core": ">=18.0.0-rc.2"

Changes since rc.1:
- feat(service): public getParent() accessor for inspecting the
  translation fallback chain (returns null at any root).
- refactor(test-app): simpler single-chain hierarchy visualization,
  no internal-API casts.
- chore: drop stray debug console.log in test-app appConfig,
  tighten ESLint mock stubs.
