Concepts docs: App routing & conversation UI architecture

[codebestia]

Write apps/web/docs/concepts-app-routing.md explaining the Next.js App Router structure under app/, the authenticated app/app/ shell and its child routes (conversations, devices, messages, profile, proposals, search, treasury), and how the conversation view composes its message list, input, and safety-number UI.

Acceptance criteria:

• The route tree is documented with a one-line purpose for each top-level route under app/app/
• The conversation route's composition (which components/hooks it pulls together) is documented at a level that orients a new contributor
• Written against the routing structure as it exists after the route-consolidation work

Hi Maintainer!, I'd love to pick this up! I can write up apps/web/docs/concepts-app-routing.md covering the App Router structure, the app/app/ shell with all its child routes, and how the conversation view components come together—all aligned with the recent route consolidation.
