chore: remove stale debug logs and spurious getInstalledInfo error logging

- Remove all APPS REFRESH debug logs from apps.dart and
  apps_provider_updates.dart (trace logging for refresh diagnostics no
  longer needed)
- Remove getInstalledInfo error log entirely: "app not installed" is
  always an expected condition, not an error. Remove printErr parameter
  and all printErr: false at call sites
