[Code Health] Modular designing

This issue is to list down possible enhancements and things-to-think-about in the design of the sensing library.

1. uploadUrl, status columns in ResourceInfo: should they be in ResouceInfoEntity ?
2. separate capture and sync modules / library: common module to talk between the 2 modules (SensingEngine). Also move the zipping and UploadRequest creation to the sync module.

Start by reading the sensing library around ResourceInfo, ResouceInfoEntity, and SensingEngine, then trace how capture, sync, zipping, and UploadRequest creation currently interact. Review whether uploadUrl and status belong in ResourceInfoEntity and document the proposed module boundaries and communication path. Done means the design decisions and required moves are clearly recorded.
