ui: uncrop the radar labels, alienize the region names, fix the contact

The feel radar's viewBox was 0 0 220 220 with axis labels centred on each spoke at r=1.26. "adventure" sits at exactly 180 degrees and is the longest axis name, so it ran 7.4px past x=0 and lost its first letter.

• The big territory watermarks on the star map now wear the same alien alphabet as the genre labels. Drawn only -- the __REGIONS debug hook still emits real names, because the headless gates match on them.

• .ab-foot wore a footer's top border after moving to the top of the About card; it gets a header's bottom rule instead.

• security.txt contact -> paul.ford@aboard.com.
