fix(FloatingButtons): group smartpicker button and drag handle together

- The button group follows the cursor now
- The button group is top-aligned to hovered paragraph node
- The drag handle button has cursor type `grab`
- Not displayed on mobile and full width view

Also removes block margin from link previews. We already have margin
between paragraphs and it makes the floating buttons look off otherwise.

Fixes: #7272
Fixes: #7604
