CI: start db container before build so it warms up during build

Moving docker compose up ahead of dotnet build lets the database container
start up in parallel with the build, so it is more likely ready by the time
EnsureDatabaseConnections and the tests run (helps the slower SqlServer
container in particular). EnsureDatabaseConnections still gates the tests via
its internal retry loop, so behaviour is unchanged.
