test(billing): add Stripe E2E test scripts for sandbox validation

- test_stripe_sandbox.py: API-only validation of all 17 products (67 tests)
- stripe_e2e_setup.py: webhook endpoint registration via ngrok
- stripe_e2e_test.py: live webhook tests with real DB verification (67 tests)
- stripe_e2e_checkout_test.py: checkout webhook tests for credit packs,
  sticky boosts, and business plan PDF purchases (40 tests)

"""
E2E test for checkout.session.completed webhook → transaction.completed handler.
Tests credit packs, sticky boosts, and business plan PDF purchases by:
1. Constructing realistic checkout.session.completed payloads with our real price IDs
2. Signing them with the active webhook secret
3. POSTing to the running dev server
4. Verifying DB state changes (credit_balance, supplier_boosts, business_plan_exports)
Prerequisites:
- ngrok + webhook endpoint registered (stripe_e2e_setup.py)
- Dev server running with webhook secret loaded
- Stripe products synced (setup_stripe --sync)
Run: uv run python scripts/stripe_e2e_checkout_test.py
