Configurable mobile-app deployments

The mobile app is now composed per deployment from a single manifest: which mesh it connects to, its display name and brand colors, and which client modules ship in its bundle. A client portal gets its own branded app by writing one JSON file — no code change.

Most module interfaces never needed an app change to begin with: pages and controls declared on the mesh render through the standard app. The manifest covers the rest — bespoke visual pieces a module brings along (a game board, a special chart) join the app at build time, and the local-mesh sidecar bakes exactly the declared variant into its release.
