watch mrr and churn

cardinal stores the recurrence schedule (customer, cadence, amount, kind) and shows the subscription list ordered by next-run date. the dashboard mrr roll-up and churn-alert badges aren't built yet.

an mrr stat at the top totaling every active subscription's monthly equivalent (annual plans normalize to /12). a churn alert when a long-time subscriber cancels — with how long they were a member and what they were paying — linked back to their dragonfly contact card.

the subscriptions list is the read-out — sort by next-run date for upcoming cycles, by customer to spot anyone with multiple subscriptions. for revenue numbers, sycamore's p&l is the source of truth in the meantime.
