feat: add ACL and Lifecycle support

Implements ACL and Lifecycle management capabilities (v0.16.0) including:
- Bucket APIs: PutBucketAcl, GetBucketAcl, PutBucketLifecycle, GetBucketLifecycle, DeleteBucketLifecycle
- Object APIs: PutObjectAcl, GetObjectAcl
- Integration: Support for Canned ACLs (private, public-read, etc.) and Full Access Control Policies
- Lifecycle Configuration: Rules, Filters, Expiration, Transitions

Verified integration with MinIO:
- Note: MinIO returns 501 Not Implemented for Canned ACLs via headers, so tests for those are skipped while Custom ACLs (XML) are fully verified.

Includes comprehensive integration tests covering all operations.
Updated ROADMAP.md to mark v0.16.0 as completed.
