Add config option to compress voxel data for oSPARC transfers using Sim4Life's built-in compression feature.

Acceptance Criteria

• Config option available to enable/disable compression
• Compression applied when uploading to oSPARC
• Decompression handled when retrieving results
• No workflow disruption for users on slow connections

Scope

• Leverage Sim4Life's native compression capabilities
• Implementation details TBD after reviewing S4L reference docs
• Accuracy impact assessment deferred to testing phase

Rationale
Reduce latency on slow connections during batch runs. Compression impact on accuracy unclear and requires investigation.
