Describe your changes

Summary

Fixed an upload issue where attachment path mappings were incorrectly resolved for entities with deeply nested compositions (e.g., Entity → Sections → attachments)
Introduced recursive path traversal (findPathToEntity) to correctly build the actual upload path when an attachment belongs to an intermediate entity rather than the direct target entity
Updated buildActualPath to accept targetEntity and distinguish between direct and nested attachment ownership before constructing the path
Updated buildEntityPath to use the attachmentPath as-is for nested attachments, ensuring uniqueness at any composition depth

Root Cause

The previous logic always built the actual path using parentEntity + compositionPropertyName + attachmentPart, which was incorrect when the attachment was owned by an intermediate composition (not the direct target entity). This caused path mismatches during upload.
