Fix document intelligence launch: port fallback and page reload after start

- services.html: Start button now reloads the page after starting a service
  (was missing reloadAfter=true), so the updated status and Launch button
  appear immediately without a manual refresh.
- services.html / service_detail.html: Launch button now appears for any
  service that has a port configured, even when local_url is not explicitly
  set. Previously, services with only a port had no Launch button at all.
- sample_data/import_existing_bundle.json: Added Document Intelligence
  (DocumentPresentationResearch_Assistant) service entry so it can be
  imported and launched from the Nexus Control Center.
