refactor(frontend): Replace Lucide icons with Phosphor icons and use Text component

- Update admin layout.tsx to use Phosphor icons instead of Lucide:
  - Users, CurrencyDollar, UserFocus, FileText, Database, Faders
- Update test-data page.tsx to use Text component for all text elements
- Update GenerateTestDataButton.tsx warning and result text with Text component
