Fix PHI scanning issues and test failures

- Remove SSN-formatted test data (123-45-6789 → MBR123456789) in edi277Resolution.test.ts
- Rephrase member ID suggestion to avoid PHI detection in edi277Resolution.ts
- Fix TypeScript compilation errors in auth-request.test.ts (add type annotations)
- Fix parseX12Response to handle A3/A4 status codes
- Fix hasDateRange to return boolean instead of string
- All 68 tests passing, PHI scanner passing (exit code 0)
