* Lazy Entry Fetch for SSE, Skip Conditional Header Check
* SSE-KMS headers are present, this is not an SSE-C request (mutually exclusive)
* SSE-C is mutually exclusive with SSE-S3 and SSE-KMS

**Critical Bug Found**: SSE-C multipart uploads were failing because:
Root Cause:
- entry.Extended[SeaweedFSSSEIV] stores base64-encoded IV (24 bytes for 16-byte IV)
- SerializeSSECMetadata expects raw IV bytes (16 bytes)
- During multipart completion, we were passing base64 IV directly → serialization error
Error Message:
"Failed to serialize SSE-C metadata for chunk in part X: invalid IV length: expected 16 bytes, got 24"
Fix:
- Base64-decode IV before passing to SerializeSSECMetadata
- Added error handling for decode failures
Impact:
- SSE-C multipart uploads will now correctly serialize chunk metadata
- Chunks will have proper SSE metadata for decryption during GET
This fixes the SSE-C subtest of TestSSEMultipartUploadIntegration.
SSE-KMS still has a separate issue (error code 23) being investigated.
Added end-to-end logging to track SSE chunk metadata lifecycle:
**During Multipart Completion (filer_multipart.go)**:
1. Log finalParts chunks BEFORE mkFile - shows SseType and metadata
2. Log versionEntry.Chunks INSIDE mkFile callback - shows if mkFile preserves SSE info
3. Log success after mkFile completes
**During GET Retrieval (s3api_object_handlers.go)**:
1. Log retrieved entry chunks - shows SseType and metadata after retrieval
2. Log detected SSE type result
This will reveal at which point SSE chunk metadata is lost:
- If finalParts have SSE metadata but versionEntry.Chunks don't → mkFile bug
- If versionEntry.Chunks have SSE metadata but retrieved chunks don't → storage/retrieval bug
- If chunks never have SSE metadata → multipart completion SSE processing bug
Expected to show chunks with SseType=NONE during retrieval even though
they were created with proper SseType during multipart completion.
