fix(whiteboard): Ensure Only Presenter Has Ability to Pan Canvas

[KDSBrowne]

What does this PR do?

This PR resolves an issue that allowed non-presenters to pan the canvas, a feature meant to be exclusive to the presenter until further controls for the infinite canvas are implemented. After this fix, only presenters will have the ability to pan the canvas, aligning with the intended functionality.

Several attempts to override the mouse events from our side have been made; however, the encapsulation and handling of the custom pointer_down event within the tldraw library prevent external interception and modification.

To align with the intended functionality, where only presenters are permitted to pan the canvas, additional modifications directly to the tldraw library will be needed. This will involve altering the event handling logic that currently enables panning on middle mouse button actions.

The specific section of code that requires changes can be found here:
