refactor(stripe): use lookup keys instead of hardcoded price IDs

[Simplereally]

• Replace NEXT_PUBLIC_STRIPE_PRO_*_PRICE_ID env vars with Stripe lookup keys
• Add convex/lib/stripeHelpers.ts with price resolution logic
• Add 27 unit tests for stripe helpers
• Fix TypeScript strict mode violations (any -> unknown)
• Delete obsolete lib/config/stripe.ts

Stripe Dashboard is now the single source of truth for pricing. Set lookup_key: pro_monthly on the price in Stripe Dashboard.

📝 Walkthrough

Walkthrough

This refactoring shifts Stripe price management from static environment-based configuration to runtime lookup-key resolution. The system now uses planType to dynamically resolve prices via new Stripe helpers, eliminating pre-check validation and simplifying the checkout flow.

Changes

Cohort / File(s)	Summary
Stripe Pricing Infrastructure convex/lib/stripeHelpers.ts, convex/lib/stripeHelpers.test.ts	New helper module introducing PlanType, PRICE_LOOKUP_KEYS constants, and utility functions (getLookupKeyForPlan, fetchPriceByLookupKey, resolvePriceForPlan, createStripeClient, getStripeErrorMessage). Comprehensive test suite validates all success/failure branches and error handling.
Price Resolution Migration convex/stripe.ts, app/pricing/checkout-button.tsx	Updated checkout flow to resolve prices at runtime using planType instead of pre-configured priceId. Removed client-side Stripe configuration validation. Replaced direct Stripe client instantiation with createStripeClient factory and centralized error handling.
Configuration Removal lib/config/stripe.ts	Deleted static STRIPE_CONFIG constant and isStripeConfigured() function that relied on environment-based price IDs.

Poem

🐰 A hop and a skip through pricing we go,
From static configs to lookups that flow,
Runtime resolving with planType in hand,
Helper functions sturdy, well-tested and grand,
Stripe's lookup keys guide us through the night! 🌙
