"my plan was to find some plugin for Catalyst of Mojo or Dancer or whatever so"

Contrary to what you said earlier:

"ok, so basically you're suggesting me to redo all negotiations to Jquery/datatables from scratch using JSON::PP and do a lot of fun with modern web frameworks.

This is exactly what I was trying to avoid"

Write a perl script query your database in a sensible way (see previous comments), return the data in JSON format. You clearly haven't read any of the documentation for the tools you've decided to use, suggesting another boilerplate module from CPAN would likely not do what you want, and be a waste of time. Also yes, you are wrong in your assumption about module numbering, and almost everything else you've written in this thread to date.
