fix(build): exclude __tests__ + .test.{ts,tsx} from prod tsc

Production build was failing because tsc compiled src/**/__tests__/*.test.tsx files
which reference vitest globals (test/expect/beforeEach) and react-router-dom — neither
imported nor in production deps. Resulted in 8 TS errors at `pnpm build` step inside
Coolify's Docker stage, blocking dev.sase.tr deploys since 2026-05-11 09:12.

Tests still run via vitest (its include pattern is unchanged).
