fix: point Admin ConfigDb at the shared SQL host

The Admin appsettings.json still carried Server=localhost,14330 — a
straggler from before the 2026-04-28 Docker migration that moved SQL
Server onto the shared Linux host. Every other checked-in appsettings
was rewritten then; this one was missed, so the Admin web UI returned
HTTP 500 on every page (SqlException, connection timeout). Repoint it
at 10.100.0.35,14330 to match.
