- Remove verificationsCache array and loadVerifications() function from verification.ts
- Remove verifyToken() and verifyTokenSync() functions (multi-replica unsafe, never used)
- Remove createVerification() function (stores unused data)
- Remove GET /verify route and verifyPage() helper function
- Remove loadVerifications() call from startup
- Remove createVerification() usage from signup route
- Update imports and test mocks to match removed functions
- Keep active 6-digit code system intact (createPendingVerification, verifyCode, etc.)
All 559 tests passing. The active verification system using pending_verifications
table and 6-digit codes continues to work normally.
