Subscription & plans — extended subscription plan limits on the backend so usage caps are actually enforced per plan, and shipped matching landing page and plans page updates so customers see the right plan structure and pricing. Admin controls for plan limits — added the admin-side controls needed to manage those usage limits per plan, so the superadmin team can adjust them without a code change. Add-on group fix — fixed the add-on group form so it stops repeatedly asking for the required "linked menu items" field once it's already filled in, which was blocking staff from saving add-on groups. Also relaxed overly strict quantity limits on add-on options that were rejecting valid values.
