feat(schematics): migrate schematics tests to Vitest

- Replace jest.config.ts with vitest.config.ts
- Update project.json to use @nx/vite:test executor
- Update tsconfig.spec.json: module es2022, vitest/globals types
- Simplify test-setup.ts (remove jest-preset-angular zone setup)
- Update nx.json production namedInputs to exclude vitest.config
