Remove JQuery code from all templates

JQuery is used in Damned Lies to perform some live JavaScript operations. The use of JQuery is not required for the simple use cases we handle, including the fact that we use Bootstrap > 5 that provides JS functions that, most of the time, provide the same features has our JQuery code.

• Identity all the files that perform JQuery operations.
• Replace the JQuery code using standard JavaScript code. Where possible, use Bootstrap’s built-in functions instead of custom code.
• Remove JQuery dependency.
