collection.aggregate.near_image(...) raises TypeError on every server from 1.29 up, before it sends anything. This adds the six media fields to __create_request and passes them on to AggregateRequest. No open issue covers it.

_AggregateGRPC.near_media spreads _parse_media(...) into __create_request. That signature has no near_image parameter, and none for audio, video, depth, thermal or imu. AggregateRequest has all six fields. The integration tests for this method carry a skip since img2vec-neural left CI, so no test ran the gRPC path.

Before, at 09c59d0, the new mock test calls the public API:

$ pytest mock_tests/test_aggregate_near_image.py -q
E       TypeError: _AggregateGRPC.__create_request() got an unexpected keyword argument 'near_image'
weaviate/collections/grpc/aggregate.py:102: TypeError
1 failed

After #2197 drops the GraphQL fallback, this path is the only one aggregate.near_image has.

Verification

$ pytest test -q          # Python 3.12.6
548 passed, 1 skipped
$ pytest mock_tests -q
72 passed

Baseline on 09c59d0 is 542 passed, 1 skipped and 71 passed, so the delta is the seven new tests. One mock test goes through collection.aggregate.near_image. The other six check the request for each media type. Reverting grpc/aggregate.py and keeping the tests gives 7 failed, all on the TypeError above. ruff check and ruff format --diff (0.14.7), flake8 and pyright 1.1.399 on weaviate/ report clean on the branch.

# not run: integration/ (needs a server with a media vectorizer)

@g-despot since #2197 routes every aggregation through gRPC, could this one go in alongside it?
