enhance: use specified manifest version in loon ffi reader (#46101)

Related to #44956

Use the exact manifest version from the path parameter instead of always
fetching the latest manifest. This ensures data consistency by reading
from the specific version that was requested.

Changes:
- Update GetColumnGroups to use transaction.begin(version) with the
specified version from the path JSON
- Replace get_latest_manifest() with get_current_manifest() after
beginning transaction at the target version
- Update Go FFI binding to call get_column_groups_by_version instead of
get_latest_column_groups
- Remove unused GetManifest function from util.cpp/util.h
- Bump milvus-storage version from 5fff4f5 to 33bf815
