fix(ui): contain finding drawer horizontal scroll to the tab bar on mobile

On narrow screens the five section tabs (Finding Overview, Remediation,
Findings for this resource, Scans, Events) did not fit, and because they
had no dedicated scroll container the overflow leaked up to the resource
card (whose overflow-y-auto implicitly resolves overflow-x to auto),
scrolling the entire drawer body horizontally.

- TabsList is now its own horizontal scroll container: triggers keep
  their intrinsic size (shrink-0) and stay on one line (whitespace-nowrap)
  so a partially-visible tab plus a thin scrollbar make it obvious more
  tabs are reachable by scrolling.
- The resource card is pinned to overflow-x-hidden + min-w-0 so no child
  can force the drawer body to scroll sideways.
- minimal-scrollbar now sets a 6px height so the horizontal scrollbar is
  actually visible on WebKit (it previously only set width).
