Assistant improvements in the extension on Android

### Issue Details

Element Blocking Using This Option For Mobile Users Isnt Great

### Proposed solution

Remove The Element Blocking Start Screen
Replace With A DarK Overlay
Implement A Small Window Box Where We Can See Element ID,Class With Nearby Elements ID,Class As Well(With A Slider For Element Selection) & In That Box We Should Be Able To Test Live Cosmetic Filters

### Alternative solution

Ublock Origin's Element Picker Functionality Copy Paste😅
