fix(desktop): gateway restart no longer clickable-by-mistake next to reconnect

Community report (X @Cobalt_Peak): Reconnect and Restart gateway in the
statusbar gateway popover rendered the same RefreshCw icon side by side,
so users triggered full gateway restarts when they meant to reconnect.

- Restart now uses a Power icon with a destructive hover tint
- Moved restart to the end of the row, after the system-panel button,
  behind a visual divider separating it from the benign actions
