Summary

Implements #16, #17, and #36 in one backend PR.

  • #36 Multi-plan catalog: Founders ($10, public), Standard ($15), Pro ($40), Business ($99), Backer ($0). Future tiers seeded but hidden/is_selectable=false. Backer email whitelist auto-assigns Founders-level access with no checkout.
  • #36 Feature + prompt gating: plan feature flags (text vs image); rolling 6h prompt windows (100 / 200 / 300 / 300 / 300). Enforced in both chat consumers when ENFORCE_SUBSCRIPTION_GATES=true.
  • #17 Token-period quotas: optional monthly_token_quota on plans + per-user override; calendar-month aggregation from PromptMetric; warn/block when reported token totals exceed cap. Null provider usage never fabricated as 0; tracked via turns_missing_token_usage.
  • #16 Token API exposure: tokens_in / tokens_out on conversation + prompt serializers (null when unknown). GET /api/finance/subscription/ returns plan + usage snapshot for the FE.
  • Checkout defaults to Founders; Stripe paid webhooks assign Founders. Registration/OAuth redeem Backer whitelist and return needs_checkout.

Companion FE PR: chat_web_app branch feature/plans-quotas-token-usage.

Test plan

  • manage.py migrate seeds five plans; admin can add Backer emails
  • Public GET /api/finance/plans/ returns only Founders
  • Register with Backer email → active Backer, needs_checkout=false, checkout rejected
  • Founders checkout + paid webhook → active Founders subscription
  • Chat turn blocked without subscription / when prompt window exceeded / when token period exceeded
  • Standard plan denies image feature; Pro/Founders/Backer allow
  • Conversation/prompt API returns null tokens when unreported, sums when present
  • finance.tests.test_plans_quotas + existing finance/checkout tests pass
