Add touch gesture to open reader menu

Browse Source 
Implements a press-and-hold gesture in the center touch zone (400ms threshold) that opens the reader menu, mirroring the Confirm button behavior. The center third of the screen is now reserved for this menu gesture, while left and right thirds continue to handle page turns. Applied to both EPUB and XTC readers.
