Add more files plugins to new DAV endpoint (#26186)

* Add more files plugins to new DAV endpoint

Also fix report plugin to properly retrieve the path from the

* In case the report is not for this plugin -> simply return to allow other plugins to get executed

* Adjust onReport tests to match new behavior
