feat(api): Add originalName field to beneficiary responses

- Add originalName to Beneficiary type in types/index.ts
- Update getAllBeneficiaries to map displayName, originalName, customName from API
- Update getWellNuoBeneficiary to include originalName in response mapping
- Use server-provided displayName instead of computing client-side

Now GET /me/beneficiaries/:id returns:
- displayName: customName || name (for UI display)
- originalName: original name from beneficiaries table
- customName: user's custom name for this beneficiary
