docs(isms): Create Update and Patch Strategy Page (ISMS-WAS-04)

### Summary
Create the Update and Patch Strategy page (`ISMS-WAS-04`) for Wazuh Agent Status.

### Scope
- Background GitHub release polling logic (5s interval).
- Release channel selection (stable vs prerelease).
- Script-based update execution workflow (`adorsys-update.sh`).
- Emergency security patching SLA and dependency scanning response.
- Update verification and payload integrity controls.

Start by locating existing ISMS pages and reading the update workflow around adorsys-update.sh, including the GitHub release polling and channel-selection behavior described in the issue. The work is done when ISMS-WAS-04 documents polling, update execution, emergency patching SLAs, dependency scanning response, verification, and payload integrity controls.
