Placed after init_db(): is_env_managed only exists once run_migrations has
added it, so an upsert before that would fail on every existing installation.
The wiring gets its own tests because the apply tests cannot cover it -- they
call apply_env_oidc_provider() directly, so deleting this call would leave the
feature dead with a fully green suite. Verified: removing the call fails the
three startup tests while all seven apply tests still pass.
They assert against the lifespan's source rather than running it. The function
is ~460 lines and starts printer connections, MQTT and schedulers; executing
it would exercise everything except the line in question. The docstring says
plainly that this proves the call exists and runs after migrations, and
proves nothing about its behaviour.
