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
