Add legacy fallback for feed V2

[idoshamun]

Summary

• add a local legacy fallback for feedV2 when the request should use the DB-backed feed path
• reuse the same configured feed query/filter helpers across feed and the feedV2 local adapter
• add coverage to verify legacy feedV2 matches feed for version 1

Verification

• pnpm run lint
• NODE_ENV=test npx jest __tests__/feeds.ts --testEnvironment=node --runInBand

🍹 The Update (preview) for dailydotdev/api/prod (at 02745d0) was successful.

✨ Neo Explanation

Routine deployment of a new application version (`ea1c225e`) across all API services and cron jobs, with accompanying database and ClickHouse migration jobs. ✅ Low Risk

This is a standard application deployment rolling out commit ea1c225e to replace 3358b668. All deployments and cron jobs are being updated solely to point at the new container image tag. The two migration Jobs (Postgres via TypeORM and ClickHouse) are being cycled with new commit-suffixed names, which is the expected pattern — the old jobs from the previous release are deleted and new ones for this release are created to run schema migrations before the new pods serve traffic.

🔵 Info — The GCP provider warning about missing default credentials is cosmetic and unrelated to this Kubernetes-only deployment; no GCP resources are being changed.
