Enhancement: Custom FullCalendar Configuration for Widgets

[sitenzo]

In this pull request, we're introducing a feature that allows you to customize the FullCalendar configuration on a per-widget basis.

What's New?

You can now set a default configuration at the plugin level. However, if you need to make specific changes for a particular widget, you have the flexibility to do so.

How to Customize Widget Configuration?

In your widget, implement the getConfig method.

public function getConfig(): array {
    return [
        // Your custom FullCalendar configuration settings go here
    ];
}

Set up the custom configuration for the widget within the getConfig method.

Merging Configurations

Behind the scenes, both the default plugin configuration and the widget-specific configuration files are merged into one final configuration for the widget. This ensures that you have full control over how FullCalendar behaves for each widget.

We believe this enhancement will provide greater flexibility and customization options for your FullCalendar widgets.
