test(creator): add integration test ensuring max-length (1000) bio preserved

[EmeditWeb]

Close #395

Add integration test for creator detail with max-length bio

Summary

• Adds an integration test that seeds a creator profile with a 1000-character bio and verifies the GET /api/v1/creators/:creatorId/profile response returns the full bio without truncation or serialization errors.
• Documents the maximum bio length as the named constant MAX_CREATOR_BIO_LENGTH = 1000 within the test.
• Uses the handler directly to avoid unnecessary app-level dependencies in the test environment and asserts response shape and headers.

Files changed (summary)

• Added: creator-detail-long-bio.integration.test.ts
• Minor update: jest.setup.ts — make test env defaults non-destructive to allow overriding DATABASE_URL during CI/local runs.

Why

• A creator bio near the maximum allowed length exercises serialization and response handling code paths. This regression test prevents accidental truncation, serialization failures, or response-shape regressions as the codebase evolves.

What I verified locally

• Installed dependencies and generated Prisma client.
• Started local Postgres via docker compose up -d postgres.
• Pushed Prisma schema:
  DATABASE_URL='postgresql://postgres:postgres@localhost:5432/accesslayer' pnpm exec prisma db push
• Ran the test successfully:
  DATABASE_URL='postgresql://postgres:postgres@localhost:5432/accesslayer' pnpm exec jest creator-detail-long-bio.integration.test.ts --runInBand

Testing Notes / Deployment

• CI must run the test with a database available (the project uses prisma db push or migrations to create schema). For CI, ensure DATABASE_URL points to the test DB and the DB is provisioned before tests run.
• The test intentionally uses a 1000-char constant to reflect the Zod schema limit in creator-profile.schemas.ts. If that limit changes, update the test constant to match.
