Refactor drag selection: Replace external library with custom implementation and add auto-scroll (#12134)

Closes #12076
Closes #11764

Replaced the `@air/react-drag-to-select` library with a custom
implementation to get better control over the selection behavior and add
auto-scroll functionality.

**What changed:**
- Removed external drag selection dependency 
- Built custom drag selection from scratch using pointer events --
@charlesBochet
- Added auto-scroll when dragging near container edges
- Fixed boundary detection so selection stays within intended areas
- Added proper `data-select-disable` support for checkboxes and other
non-selectable elements

The new implementation gives us full control over the selection logic
and eliminates the external dependency while adding the auto-scroll
feature that was **not** requested 😂

**Auto Scroll**

- Record board column height not extending to the bottom (styling issue
I found while working on this)
