feat: add manual database session handling with rollback on exception

[seapagan]

Add a second database dependency that will NOT call the explicit .begin() on the session, so the session will only be opened when first accessed and should allow multiple database calls in the same route.

Should allow closing #768

In future this may be the default functionality but for now lets leave the auto-commit dependency as default.
