feat(map): award filters with boundary overlay in grid mode

- Grid-mode top bar replaced with award filter chips (All/DXCC/VUCC/
  WAPC/WAJA/WAZ/WAS) showing live progress (count/target)
- New AwardBoundaryOverlay renders real administrative boundaries
  (provinces/prefectures/CQ zones/states/countries) with the VUCC visual
  language: yellow boundary lines, green fill for worked regions, labels
- Boundary assets packaged from public GeoJSON (DataV China, Japan land,
  HB9HIL CQ zones, Natural Earth states/countries) with ADIF match keys:
  WAPC province codes, WAJA ADIF prefecture numbers, US state abbrs,
  ARRL DXCC entity codes
- GridQso extended with dxcc/country/cqz/state parsed from LoTW report
  (qso_qsldetail); AwardCalculator derives six-award progress; STATE is
  interpreted per DXCC entity (ADIF 'STATE depends on DXCC')
- Grid-mode toggle pill floated at map top-right (Grid mode / Satellite mode)
- New tests: AwardCalculatorTest (9 cases), LoTW award-field parsing (3 cases)
