Fix middleware order so dashboard context runs after session

Middleware execution order was wrong - dashboard context middleware was running
BEFORE SessionMiddleware, so request.session didn't exist yet.

Fixed execution order:
1. ProxyHeadersMiddleware
2. SessionMiddleware
3. CORSMiddleware
4. tier_limit_middleware
5. auth_middleware
6. dashboard_context_middleware
