fix(test): sync Appointments.test.tsx with portal refactor

- Update import to use .tsx source instead of outdated .js
- Change header assertions from X-Impersonation-Session-Id to Authorization Bearer
- Change confirmed badge text from "✓ Confirmed" to "Confirmed"
- Add allowImportingTsExtensions to tsconfig (required for .tsx imports with bundler moduleResolution)
