build: update qdrant-client to upstream >=1.17.0

The fork (cbcoutinho/qdrant-client fix/fusion-score-threshold) has been
merged upstream as PR #1138 and released in v1.17.0. Remove the git source
override in [tool.uv.sources] to unblock clean PyPI publishing, since git
dependencies are excluded from wheels.
