Replaced the placeholder spec with a real unit test that instantiates PortfolioService, stubs dependencies, calls

getSummary, and asserts the returned summary fields (including annualizedDividendYield and computed totals). The new test
  lives in apps/api/src/app/portfolio/portfolio.service.spec.ts.
