d3dc03c85a s3api: resolve volume data encryption in CopyObject SSE flows (#11646) (#11683)
* s3api: resolve volume data encryption in CopyObject SSE flows (#11646)

* s3api: honor bucket-default KMS key on copy and fix transformed-upload metadata

- Synthesize the destination bucket's default encryption as request
  headers before any SSE evaluation, so the configured KMS key ID and
  bucket-key setting reach the copy paths instead of only a boolean.
- uploadTransformedChunkData returns the upload result so callers record
  the uploader's cipher key AND compression decision; a wrongly cleared
  IsCompressed made transformed copies unreadable.
- decompressChunkVolumeCipher fails loudly when a compressed chunk does
  not decompress, instead of uploading still-compressed bytes marked
  uncompressed.
- copyMultipartSSECChunk now strips the volume cipher and re-encrypts on
  upload like the other transform paths.
- The ciphered inner upload now uses the caller's private BytesBuffer.
