Moh e2e06be86e test: add comprehensive automated test coverage
- Vitest multi-project setup (unit / integration / component)
- Real-Postgres integration harness via in-process PGlite (TEST_DATABASE_URL
  override), migrations applied per worker; production code untouched
- Unit: routing, locale, validation/Zod schemas, metadata, mail, site-theme,
  marquee, media, portfolio helpers, plus architecture-rule tests
- Integration: Prisma data layer, API routes, and all server actions
- Component: UI primitives and form components (jsdom + Testing Library)
- 371 tests passing

* Integration database wiring.
*
* - If TEST_DATABASE_URL is set, the real `lib/prisma` singleton is used unchanged,
* pointed at that Postgres (e.g. the Docker instance). Migrations are applied once
* by the global setup; files run serially and truncate between tests.
*
* - Otherwise, `lib/prisma` is mocked with a Prisma client backed by an in-process
* PGlite database (Postgres compiled to WASM) — real Postgres semantics, fully
* isolated per worker, no external server. Production code is never modified.
