Original cherry-pick message follows:

Merge pull request #1751 from Altinity/feature/antalya-26.3/pr-1631

Antalya 26.3: Fix condition for using parquet metadata cache
# Conflicts:
#	src/Storages/ObjectStorage/StorageObjectStorageSource.cpp
#	tests/integration/test_storage_iceberg_with_spark/test_read_constant_columns_optimization.py
Kept "ours" (antalya-26.5) side of the conflict in
`StorageObjectStorageSource.cpp`. The actual fix from #1751 — wrapping
the format comparison with `Poco::toLower` and using lowercase
`"parquet"` — was already present on antalya-26.5. The "theirs" side
additionally included `&& use_native_reader_v3`, which is not part of
#1751's diff (it was pre-existing context on antalya-26.3) and does not
exist on antalya-26.5, so it was not introduced. `configuration->format`
(field access on antalya-26.5) is kept instead of
`configuration->getFormat()` (method used on antalya-26.3).
