docs: resolve both governance gates (OPEN-01, Horizon 2 Phase 0)

OPEN-01 (scholarly-review-log.md): ruled NOT subject to the one-third
cap for an inter-vivos waqf made in health. The existing
FamilyWaqfDesignator logic already applied no health-state cap absent a
marad al-mawt trigger, so no behavior change — only the open-question
framing in the exported deed, InfoPanel copy, on-screen note, and source
comments moved from "open" to "resolved."

Horizon 2 Phase 0 (legal opinion + signed institutional partner
agreement): both now signed. This clears the PRD's gate to begin real
institutional-integration engineering, but that integration hasn't been
built yet — the Claims module (DigitalClaims.svelte, claims.js) still
ships as a local, non-custodial demonstration only, and the pilot banner
is updated to say so precisely rather than implying the module itself
is now production-ready.

Updated README.md and deploy/DEPLOY.md to match.
