wrong use of systemd templates for validation cleanup service

Expected Behavior

There are several systemd based cleanup timers and affiliated services (one for each workflow) that are configured to remove files uploaded to the validation service more than two weeks ago.

We would expect the timers to trigger their respective cleanup services.

Actual Behavior

Due to a bug in this task, we do create multiple services, but as the timer isn't implemented as a systemd template, there's only one timer, which leads to erroneous naming of the service and subsequently use of a non-existent search path.
