fix: [HUDI-3055] Fix hardcoded GZIP compression codec in HFileUtils

[ZZZxDong]

Describe the issue this Pull Request addresses

Fix issue #14963: Ensure that compression codec configuration is respected across the board.

Changes here only affect routes when codec is null or empty, hence default value should be respected.

Summary and Changelog

• Modified HFileUtils.getHFileCompressionAlgorithm() to use HFILE_COMPRESSION_ALGORITHM_NAME.defaultValue() instead of hardcoding CompressionCodec.GZIP
• This ensures the method respects the configured compression codec default value

Verify this pull request

This pull request is already covered by existing tests:

• TestHFileUtils.testGetHFileCompressionAlgorithm() - tests all compression codecs
• TestHFileUtils.testGetHFileCompressionAlgorithmWithEmptyString() - tests empty string case
• TestHFileUtils.testGetDefaultHFileCompressionAlgorithm() - tests default value case

Impact

Ensure that compression codec configuration is respected across the board, Hfile uses hfile default compression for now.
