[AGIPD][Correct] Improve errors when no lit frames to correct

Description

This MR is related to these tickets:

• https://redmine.xfel.eu/issues/169387
• https://redmine.xfel.eu/issues/154958

Changes proposed in this MR:

• When no data trains to correct, skip plots with a warning before plotting raw or corrected data.
• When no lit frames are available to correct, emphasize this by replacing the empty list with a message of no frames to correct.
• Before going into litframe cell, check if any trains are in the run for the selected module to correct in the first place.
• custom \warningbox Latex command included with the preambles in the finalize script.
