Mobile: bump autonomous plane speed from 28 s → 16 s per traversal

Browse Source 
Mobile screens are smaller and users glance at them for less time,
so the 28-second full-traversal on desktop felt sluggish there.
BASE_SPEED is now 1/16 on mobile vs 1/28 on desktop. The touch
boost (×6) still stacks on top, giving a sub-3-second sprint when
the user holds a finger down.
