fix(build+worker): restore seedDatabase export + DISABLE_WORKER_CONSUMER guard

1. packages/database/seed.ts: restore re-export of seedDatabase.
moduleResolution:node ignores package.json exports field — TypeScript
resolves @repo /database/seed to root seed.ts. Without the re-export,
tsc sees no seedDatabase export → TS2339 build failure.
Runtime still uses dist/src/seed.js (via exports field) which is
compiled CJS with no TypeScript syntax.

2. apps/whatsapp-worker/src/index.ts: add DISABLE_WORKER_CONSUMER guard.
Both Railway and HuggingFace workers share the same BullMQ/Redis queue.
When HuggingFace wins a send-message job, it fails with SSL EPROTO
(HF cannot reach graph.facebook.com). Setting DISABLE_WORKER_CONSUMER=true
on HuggingFace keeps the bridge running (accepts forwarded webhooks) but
stops it from consuming jobs — only Railway's worker sends to Meta.
