feat: Add client main shell with bottom navigation

Introduces the new client_main feature package, providing a main shell with bottom navigation for the client app. Updates routing to use /client-main instead of /client-home, adds localization for new tabs, and implements navigation logic, UI, and tests for the main shell. Also refactors create_order module bindings and cleans up unused dependencies.
