To simplify logic in the system, a child lifetime scope is created for
each distinct configuration instance that is processed by Recyclarr. The
main driver for this is to avoid objects being reused between instances
and thus needing setup & teardown logic to deal with state.
It was previously located in Common, which I'm trying to gradually get
rid of. Supported services are ultimately determined by what is in the
guide, so that seems like the best place for it.
The removal of Sonarr v3 support (commit d45563cf) introduced a bug
resulting in media naming no longer working due to the `:4` key suffix
not being checked anymore.
Additionally, there were some tests under `src/tests/` that needed to be
moved to `tests/`. One of these tests in particular helped identify this
bug. Those tests have been moved to the appropriate location.
