Fix back gesture to use logical screen coordinates

Browse Source 
Changed the fallback corner gesture detection to use logical (orientation-mapped) coordinates instead of native panel coordinates. This ensures the gesture area remains in the visual top-left corner across all screen orientations, particularly for screens without a header or Back button target like the reader.
