[PS-1222] Remove appBlurClick throughout the popup and web code (#3208)

* Remove appBlurClick throughout the popup code

`appBlurClick` leads to focus being lost/reset for assistive technology users. It should not be necessary in any case - if focus does need to move after an action, explicitly set it somewhere programmatically using `focus()` rather than relying on browser heuristics

* Remove now redundant blur-click directive
