Log Vercel request IDs for API requests

[chrarnoldus]

Summary

• persist the inbound x-vercel-id header in api_request_log.vercel_request_id
• limit and normalize the header through the existing gateway header helper
• add route coverage and a generated Drizzle migration in a separate commit

Validation

• pnpm format
• targeted oxlint on changed TypeScript files
• pnpm --filter @kilocode/db typecheck
• POSTGRES_URL=... pnpm drizzle check
• changed-package typecheck exceeded the 120-second sandbox limit
• focused Jest suite could not initialize because Docker/Postgres is unavailable in the sandbox; all failures occurred during database setup
