Entity Analytics - Attachment to Cases

**Problem Statement**
The current Entity Analytics experience lacks a formal "bridge" to case management. Threat hunters identify risky entities (users, IPs, hosts) during their investigation, but there is no streamlined mechanism to persist those findings into a formal case record. This creates a fragmented workflow where hunters must manually copy-paste or re-find data, leading to context loss and inefficient handovers.

**Value proposition**
Provide an user experience to allow the users to attach entities to a case from various places such as flyout, or etc.
