fix(map): award boundary fixes — HK/MO labels, MO DXCC entity 152, antimeridian ring closure

- wapc/dxcc assets: add Hong Kong & Macau labels (forceLabel) and MO boundary in dxcc
- AwardBoundaryOverlay: rings split at antimeridian no longer close() per segment — removes spurious Russia cross-continent chord
- AwardCalculator: Macau DXCC entity 330 -> 152 (+test)
- Settings LoTW dialog: add sync duration hint (zh/en)
