/**
* Shared e2e harness for migrated Nest modules.
*
* Gives each module e2e test a throwaway in-memory SQLite db (the same shape the
* shared connection exposes), a seed helper for demo data, and a session-cookie
* signer that produces tokens the REAL JwtAuthGuard accepts — so e2e tests cover
* the actual auth path end-to-end, not a stubbed guard.
*
* Wire it in a test with `vi.mock('../../src/db/database', () => ({ db, ... }))`
* using the db returned here, then build the Nest app under test.
