fix(parcel-sync): sync progress visible during GPKG/bundle export

3 bugs fixed:
- syncLayer was called without jobId -> user saw no progress duringSync
- syncLayer set status:'done' prematurely -> client stopped polling before GPKG phase
- syncLayer errors were silently ignored -> confusing 'no features in DB' error

Added isSubStep option to syncLayer: when true, keeps status as 'running'
and doesn't schedule clearProgress. Export routes now pass jobId + isSubStep
so the real sync progress (Descărcare features 50/200) is visible in the UI.
