remove min-ratio setting and enforcement

- Drop minRatio parameter from container.adjustBoundary; guard is now
  newLeft/newRight <= 0 (i.e. only prevent a pane from inverting)
- Remove _getMinRatio() helper and all call sites in windowManager.ts
- Remove Window Sizing preferences group and min-window-size-percent
  spin button from prefs.ts
- Remove min-window-size-percent GSettings key from schema XML
