Adds electoral nuclei, leaderships, updates, and WhatsApp invite flows behind campaign auth, plus the consolidated schema migration that Vercel applies on deploy.
Local dev and the test suite previously defaulted to the live production
Neon database, and running the tests mutated prod data. Add guardrails plus
a proper local Postgres + migrations workflow so production can't be hit by
mistake:
- docker-compose: local Postgres 17 (matches prod) + auto-created teqo_test
- dev guard refuses a non-local DATABASE_URL; tests refuse non-_test databases
- .env.test isolates the suite; vitest/playwright load it and fail closed
- Payload migrations set up (push disabled); build runs `payload migrate`,
so deploys apply pending migrations to prod automatically
- baseline `initial` migration + idempotent consent.text varchar->jsonb fix
- `pnpm db:pull` copies prod content locally, excluding supporter PII
- docs (README, AGENTS.md) + agent skills for the local-db/migration workflow
