Enable drag scrolling for web interface

[nadavrak]

Description

Enables drag scrolling functionality for web interface by adding mouse and trackpad to the dragDevices in ScrollConfiguration.

Problem

Currently, web users can only scroll using the scrollbars, which limits usability.

Solution

Added ScrollConfiguration with expanded dragDevices to include mouse and trackpad support.

Testing

Tested on:

• Chrome

Added code to build method:

// Add a ScrollConfiguration wrapper with dragDevices including PointerDeviceKind.mouse
return ScrollConfiguration(
behavior: ScrollConfiguration.of(context).copyWith(
dragDevices: {
PointerDeviceKind.touch,
PointerDeviceKind.mouse,
PointerDeviceKind.trackpad,
},
)

Not sure if I understand the problem... https://maxim-saplin.github.io/data_table_2/#/datatable2 - this sample doesn't have any issues with mouse, trackpad or touch scrolling (tested on desktop and mobile)
