Offer both monthly and yearly per-seat billing (currently yearly-only).

Scope

  • Paddle catalog: add a monthly recurring price alongside the existing yearly one (sandbox first; both under the existing "Cairn Commercial License" product). Price points are Nikola's call — current yearly is the $48/seat placeholder.
  • Webhook: derive license validity from the billing period of the transaction (monthly txn → ~1 month + grace margin, yearly → 1 year + margin) instead of the hardcoded 1 year. Store the billing cycle on the record.
  • Buy flow (cairn-site account.html): billing-cycle toggle (Monthly / Yearly) selecting the right priceId; show effective per-seat price for each cycle.

Depends on the renewal-refresh issue — monthly subscriptions make "new key every month" absurd, so refresh-in-place must land with or before this.

Decision needed at greenlight (Nikola): monthly and yearly price points.

Acceptance: sandbox checkout in both cycles → license issued with correct expiry; renewal simulation extends it (see refresh issue); UI shows both options.
