BUG: 308948

In order to disable JPEGLossLess kipi-plugin in digiKam and to use internal JPEG transform implementation intead,
I renamed class to wrap metadata actions as file actions.
Simple transform image calls (rotate and flip) will be hosted later in this manager.

Add a custom model which implemented the light table right/left roles,
removed them from global code.
Use methods provided by DCategorizedView for next/prev/first/last navigation.

CCBUG: 280082

To be compatible with current implementation of LightTable, thumbbar must use a single selection. We will study later multiple selection mode...
