fix(parcel-sync): progress display stuck + numbers jumping during sync

2 bugs:
1. After Magic/base download completes, progress bar stayed stuck at
   77% because exportProgress was never updated to 'done' client-side.
   Fix: set progress to 'Finalizat' + 100% after successful blob download.

2. syncLayer overwrote the export route's weighted percentages (0-100)
   with raw feature counts (50/200), causing progress bar to jump.
   Fix: when isSubStep=true, sync writes phase/note/phaseCurrent/phaseTotal
   but preserves the parent route's downloaded/total weighted values.
