[ME]: Add search filters

[tkohr]

Description

This PR introduces a new search-filters.component for the md-editor app. It is displayed with a first filter allowing to filter on editor/user on the allRecords list. The component is also displayed on the myRecords list, but empty for now as the editor filter does not make much sense here.
