/**
* Interface for buttons that define their own fixed position and group.
*
* Buttons implementing this interface will automatically override the position
* and group parameters passed to ButtonBar::addButton(), ensuring they always
* appear in their designated location regardless of what the developer specifies.
*
* This is useful for buttons that should always appear in a consistent location
* across the backend, such as the ShortcutButton which always appears in the
* top right corner.
*
* Example implementation:
*
* ```
* class MyButton implements ButtonInterface, PositionInterface
* {
* public function getPosition(): string
* {
* return ButtonBar::BUTTON_POSITION_RIGHT;
* }
*
* public function getGroup(): int
* {
* return 90;
* }
* }
* ```
*
* Usage:
*
* ```
* $button = $buttonBar->makeMyButton();
* // Position and group are ignored - button defines its own
* $buttonBar->addButton($button);
* ```
