Closes#1024

Re-open the zarr group after da.compute() in _write_raster_datatree so that the main process picks up metadata written by ome-zarr-py's delayed write_multiscales_metadata() task, which runs in a subprocess under the 'processes' scheduler and leaves the original in-memory GroupMetadata stale. The fresh group is returned to _write_raster so the subsequent spatialdata attrs write also uses the correct on-disk state.

Added tests.

fix: use use_consolidated=False when re-opening group after compute
b12778d
The re-open after da.compute() was inheriting stale consolidated metadata,
which caused KeyError when newly written children (e.g. labels3d_multiscale_xarray)
were not yet reflected in it. Passing use_consolidated=False forces zarr to
read group membership directly from the store instead.
