fix(paycraft): correct Razorpay plan billing cadence for quarter/semiannual

[therajanmaurya]

Problem

syncProductToRazorpay mapped every non-month interval to a yearly Razorpay plan with a hardcoded multiplier of 1. Pro Quarterly and Pro Semiannual products would be created as yearly-billing plans — a revenue mismatch (customer pays the quarterly/semiannual price but is billed once a year). Razorpay plans are immutable after creation, so this had to be fixed before any provider sync.

Fix

Added razorpayPlanCadence() mapping every PayCraft billing interval to the correct Razorpay period + multiplier:

interval	Razorpay plan
month	monthly × 1
quarter	quarterly × 1
semiannual	monthly × 6 (no native half-yearly period)
year	yearly × 1

Unknown intervals now throw (surfaced as a failed sync) instead of silently minting a wrong-cadence plan. Stripe path was already correct. tsc --noEmit clean.

📝 Walkthrough

Walkthrough

Adds a BillingInterval union type and a razorpayPlanCadence helper to dashboard/lib/razorpay-product-sync.ts. The helper maps PayCraft intervals (month, quarter, semiannual, year) to Razorpay period and numeric interval multipliers, and throws on unrecognized input. syncProductToRazorpay is updated to use this helper and accept the broader interval type.

Changes

Razorpay Billing Interval Mapping

Layer / File(s)	Summary
BillingInterval type and razorpayPlanCadence helper dashboard/lib/razorpay-product-sync.ts	Exports a BillingInterval union ("month" | "quarter" | "semiannual" | "year") and adds razorpayPlanCadence, which returns { period, interval } for each supported cadence (semiannual maps to monthly × 6) and throws for unrecognized inputs.
Integration into syncProductToRazorpay dashboard/lib/razorpay-product-sync.ts	Widens the interval parameter type to BillingInterval | string | null and replaces the prior coarse month/year fallback with razorpayPlanCadence(interval) to set period and interval on client.plans.create.

Poem

🐇 Hoppity-hop through the billing land,
Monthly, quarterly—now perfectly planned!
Semiannual gets its six-month due,
No more guessing what cadence to do.
The rabbit checks intervals, throws on the rest,
PayCraft and Razorpay, synced at their best! 🥕
