fix(sys-bar): fix hover bounce, horizontal overflow, add collapsible sections

- Hover info strip is now absolute-positioned above the bar (opacity fade
  with delay-500) so it never shifts the bar layout — fixes the bounce
- Panel widened to w-80 with overflow-x-hidden — fixes horizontal scroll
  caused by sub-components hardcoding w-72 inside the padded panel
- All panel sections are now collapsible (Access open by default, others
  closed) — reduces vertical crowding; matches launcher_cfg pattern
- Section headers show current state inline (access level, theme name/mode)
- Admin section groups cfg + debug trigger together cleanly
- Bar transitions use duration-200 for snappier feel without bounce
