docs(isms): Create Architecture Page (ISMS-WAS-02)

### Summary
Create the Architecture documentation page (`ISMS-WAS-02`) for Wazuh Agent Status.

### Scope
- Client-Server topology (privileged daemon vs Tauri UI client).
- Network position & Localhost TCP socket (`127.0.0.1:50505`).
- Plaintext data exposure & local IPC communication.
- Trust boundaries and privilege containment.
- Availability posture and self-healing daemon restarts.
- Evidenced security controls and open architecture gaps.

Start by locating the existing documentation structure and the Wazuh Agent Status daemon, Tauri UI client, and localhost socket entry points. Verify the client-server topology, privilege boundaries, IPC exposure, restart behavior, and security controls against the implementation. Done means a new ISMS-WAS-02 architecture page covers every listed scope item, evidence, and open gap.
