fix(ui): declutter device page header — compact tool buttons

- WinBox/RemoteWinBox/SSH: replace big accent CTAs with compact
  bordered tool buttons (text-[10px], h-3 icons, border-default)
- SimpleModeToggle: shrink from pill-button group to inline segmented
  control (text-[10px], accent-soft active state)
- Edit/Delete already icon-only ghost from previous commit
- All tool buttons now visually consistent — small, bordered, receding
- Result: header reads as a compact control strip, not a CTA row
