[EPIX100][PNCCD][CORRECT] Display creation time for retrieved constants

This is related to issue: https://git.xfel.eu/calibration/planning/-/issues/171

Description

This fixes the missing display for which constants were retrieved and with which timestamp.

As pnccd and epix already have calcat_interface and fragment used. I added the fix for both.

The ccvs are displayed using markdown with a link to the calcat page.
