Adding reset functionality for column preferences

[Rocker810]

Closes #14414

This PR adds a reset functionality for column preferences in the entry table settings. When users override the clear() method in preferences, it now properly resets both the main table preferences and column preferences to their default values.

Changes Made:

Added getDefault() static method to ColumnPreferences class to return default column configuration
Overrode clear() method in JabRefGuiPreferences to reset main table and column preferences to defaults
Ensures that when preferences are cleared, the entry table columns are restored to their original state

Please do not close prs and open new ones. You can just push to your remote branch. GitHub will handle everything else. But by reopening a new pr the reviewers will loose context. That makes the process complicated, slower and more annoying.

@calixtus Thank you for the guidance, I am sorry for the confusion caused. This is my first PR, and I was seeing how the process works. I accidentally closed it while exploring the interface.

No problem, we are here to help. Only condition is that people really try to do their best and not let ai do the talking or the coding, because JabRefs mission is to educate people about coding and open source.

No. I don't think that you understood the assignment. Target is to get rid of the defaults map. Your last commit won't work at all.

This issue is not just about coding some simple hacks. You need to adapt the generic getColums methods.
