fix: support email queue

[Kinfe123]

Summary

• Process newly queued enterprise support emails with a post-response task after the form submission is saved.
• Move the shared queue claiming, retry, payload validation, and send logic into website/lib/enterprise-support-email-queue.ts.
• Keep the authenticated cron endpoint as a retry/backfill worker and document the required worker secret in .env.example.

Root Cause

Enterprise support submissions were saved and queued, but delivery depended on the scheduled worker. With the daily cron cadence, a request submitted after the cron run stayed pending until the next day, and missing worker auth configuration could prevent manual or scheduled processing.

Validation

• pnpm --dir website exec tsc --noEmit
• pnpm exec oxfmt --check website/lib/enterprise-support-email-queue.ts website/app/api/enterprise-support/email/process/route.ts website/app/api/enterprise-support/route.ts website/.env.example
• git diff --check -- website/.env.example website/app/api/enterprise-support/email/process/route.ts website/app/api/enterprise-support/route.ts website/lib/enterprise-support-email-queue.ts

Summary by cubic

Process enterprise support emails immediately after form submission, removing the daily-cron delay. Centralizes queue logic in a shared module and documents the required worker secret.

• Bug Fixes

  • Process queued emails right after save via a post-response task, so delivery isn’t blocked by cron.
  • Move claim/retry/validation/send into a shared queue module; cron endpoint is now for retry/backfill with a bounded limit.
  • Improve failure handling with payload validation, exponential backoff, and exhaustion tracking.

• Migration

  • Set ENTERPRISE_SUPPORT_EMAIL_WORKER_SECRET (or CRON_SECRET) in .env to authorize the retry worker.
