Redesign trip, progress, and achievement share cards with premium
sports-media aesthetic. Remove unused milestone/context achievement card
types (only used in debug exporter). Fix gold text unreadable in light
mode. Fix sport selector to only show stroke on selected sport.

Adds debug-only DebugShareExporter that bulk-exports ~298 shareable
image variations (achievement cards, progress cards, trip cards, icons)
to Documents/DebugExport/ for visual QA. Also adds a button to populate
all stadium visits for testing the fully-unlocked app state.
