fix(core): memory leaks from connected callback states

- Added tests to ensure that the checked state of checkboxes and radio buttons resets to their native defaults upon calling the reset method.
- Improved the handling of observers in form controls to prevent duplication after reconnecting.
- Enhanced the Select component to stop observing removed options and to reset selected options to their native defaults.
- Added accessibility tests for the PagePanel component to ensure compliance with axe standards.
