Allow users to set custom display names for their beneficiaries
(e.g., "Mom", "Dad" instead of the real name). The custom_name
is stored per-user in user_access, so different caregivers can
have different names for the same beneficiary.
Changes:
- Migration 009: Add custom_name column to user_access
- API: Return customName in GET /me/beneficiaries endpoints
- API: New PATCH /me/beneficiaries/:id/custom-name endpoint
- Types: Add customName to Beneficiary interface
- api.ts: Add updateBeneficiaryCustomName method
