GET /api/version now reads the latest version from Docker Hub image tags (the
actual update channel clinics pull), falling back to the GitHub release if
Docker Hub is unreachable, with a shorter 1h cache and a `?refresh=1` bypass.
Settings → About & updates gains a "Check for updates" button that forces a
fresh, cache-bypassing lookup.

Add public GET /api/version (current version + GitHub-release update check,
cached, fail-soft) and GET /api/network (detected LAN addresses). Accept
localhost/private-LAN origins in CORS and Better Auth trusted origins via a
shared isAllowedOrigin helper, so staff can reach the app over the clinic
network. The seed-demo.ts fake test data is removed.
