Small CI flakiness fix and performance tweak (#3780)

* perf(ci): use Turbo to schedule both `lint` and `test` tasks at once

* fix(ci): wait until service containers are initialized for tests

This is achieved by adding a health check to the containers, and
instructing the CI workflow to wait until the containers are healthy.
Not doing this wait risks spurious CI failures due to DB migrations
being applied before the DB even starts.

* chore(turbo): use locally installed schema in new Turbo override file

On the latest versions of Turbo, this ensures that the used schema is
always in sync with what's available in the installed Turbo version,
which is something that has already caused confusion to me before.
