feat(p6): route-admin demo + route smoke; P6 verification green

Task 6.6: apps/route-admin (Vite, port 5176) — create bindings, simulate a
message (preview-first, no send), see color-coded per-destination decisions
with reason codes + preview, approve/deny REVIEW rows; built on the
community-web SDK via CommunityProvider.

scripts/smoke-route.mjs: 3 MANUAL bindings → 'party at 9 PM' → children(CHILD)
DENY / adults+seniors REVIEW / 0 sends on simulate; approve → exactly one
sandbox forward; AUTOMATIC safe binding auto-forwards via RouteProjector.

P6 verification: 63 tests green, pnpm -r build all packages+demos, boundary
passes and fails on community-web→service, route smoke PASS, prior smokes
(realtime/inbox/support/adapter) PASS.
