fix: disable logging --host (breaks Anaconda), add integration config

The kickstart `logging --host` directive stalls Anaconda install —
likely firewall blocks UDP syslog or Fedora 43 Anaconda has issues
with it. Commented out for now. Syslog listener infrastructure is
in place and ready once we resolve the Anaconda/firewall issue.

Added vitest.integration.config.ts for running integration tests:
  pnpm exec vitest run --config vitest.integration.config.ts

All 21 integration tests pass, serial console rsyslog forwarding works.
