chore: regenerate all poetry.lock files for datasets 4.4.1

Regenerate all service and job lockfiles to pull in datasets 4.4.1
which includes the Nifti feature type. This fixes the CI failures
where services couldn't import Nifti from datasets.

Updated lockfiles:
- libs/libapi/poetry.lock
- services/admin/poetry.lock
- services/api/poetry.lock
- services/rows/poetry.lock
- services/search/poetry.lock
- services/sse-api/poetry.lock
- services/webhook/poetry.lock
- services/worker/poetry.lock
- jobs/cache_maintenance/poetry.lock
- jobs/mongodb_migration/poetry.lock
