atsunatsu a64f9c80b9 fix(map): split award boundary rings at antimeridian + anchor projection
DXCC (Russia/Fiji/Antarctica) and WAZ (Pacific CQ zones 1/19/31/32) polygon
rings cross ±180. The old overlay normalized every vertex to [-180,180)
independently, folding far-side vertices onto the opposite screen edge and
drawing a spurious line sweeping across the whole map (esp. at low zoom:
DXCC horizontal/vertical lines, WAZ extra long edges).

Split each ring into contiguous segments at the antimeridian, then project
each segment anchored on its first vertex with continuous longitude offsets
(no per-vertex fold). Ring geometry stays intact while panning/zooming.
