Resolve "feat(ui): add possibility to remove fiducial distances from the current slice"

Description

Closes #1221 (closed)

We should add the possibility to remove all added fiducial distances from the current slice.

How to test it?

Manual testing and debug data to verify if the relevant fiducial data is being correctly deleted.

• Change the remove_all slot to remove_distances_from_current_slice for distance in sight_viewer (volume_rendering.xml line 348). Then check if we add distances in one slice, they are removed correctly.
• Check in an other app where there is a "remove distances from current slice" button.
