Fix tooltips go offscreen and arrowless on mobile

- Fix tooltip overflowing when hovering on script selection options
  (None, Standard, Strict, All) on UI. This issue was caused because
  these options had `white-space: nowrap` so they're rendered together.
  However, as tooltips are rendered inside of the same DOM element with
  their triggering elements, this style was propagated and caused
  overflow content to overflow on smaller screens. This commit adds
  `white-space: initial` on tooltip overlay/container to stop the
  propogation and fix the issue.
- Fix overflow issue revealed another issue with tooltip arrow
  rendering. When tooltip is shifted from its default position (top) to
  bottom on smaller screens when there are not enough space on top, the
  tooltip arrow did not change its position and still stayed on bottom.
  This was caused because of using wrong reference to get current
  placement of the tooltip. The issue is fixed by using the reference
  from `useFloating` function.
- Improve `DevToolkit` component to be less intrusive during tests. The
  DevToolkit is now non-interactable except its buttons for easier
  testing of tooltips on smaller screens. A new close button is also
  added on the box, so it can be closed completely if desired.
