feat(security-posture): add Security Posture to Hub sidebar (ref #615)

The sidebar is data-driven from /api/v1/hub/public/menu, which aggregates
/usr/share/secubox/menu.d/*.json. secubox-security-posture shipped no menu.d
entry, so it never appeared in the nav despite being wired into the monitoring
page content.

- Add menu.d/security-posture.json (category wall, icon level dial, /security-posture/)
- Rename www/dashboard.html -> www/index.html so nginx serves /security-posture/
- Install menu.d into /usr/share/secubox/menu.d in debian/rules
- Bump changelog 1.0.0-1 -> 1.0.1-1
