What changed in this PR

This PR exposes raster data types and no-data values in batch job results so the backend can reload its own STAC output through load_stac without guessing those values.

Changes:

• Adds asset-level metadata for STAC 1.1 and raster-band metadata backfilling for STAC 1.0.
• Updates dummy data and result-response assertions.
• Documents the change and bumps the development version to 0.142.0a4.

File	Description
tests/​test_views.py	Adds expected raster metadata to job-result responses.
openeo_driver/​dummy/​dummy_backend.py	Adds a raster data type to the sample TIFF asset.
openeo_driver/​backend_/​_geopyspark.py	Exposes and backfills raster metadata in STAC assets.
openeo_driver/​_version.py	Bumps the development version.
CHANGELOG.md	Records the metadata exposure change.

🟡 Changes recommended

The new regression tests lack a required Flask context, and raster metadata enrichment skips assets without a separate band list.

Existing raster bands skip asset metadata enrichment

openeo_driver/​backend_/​_geopyspark.py:488

For STAC 1.0 assets with existing raster:bands but no separate bands list, this guard skips enrichment and omits asset-level data_type and nodata from the raster entries. Move enrichment outside if bands, keeping the band-count requirement only for synthesizing a new array, and add a regression test for absent or empty bands.
