mikkeli 8ee3d4cde5 Correct admin build: must use full Japan extract, not a sub-region ...

Verified on the Orin. A Shikoku extract yields only admin_level=4 prefecture
rows with no country record, and drive_on_right=1 on every one, so tiles built
against it route as right-hand traffic. The full Japan extract yields the
JP country row with drive_on_right=0.

The failure is silent, so every build now verifies the country row before
tiles are considered usable.
