Customer Profile Model

CustomerProfileResponse mirrors /store/customers/me — id, first_name, last_name, email, phone, addresses, metadata. CustomerProfileRequest is the partial update payload posted by the manage-profile screen.

1. fromJson is tolerant to missing fields — every field optional except id.
2. Edit screens construct a CustomerProfileRequest with only the changed fields.
3. Response is consumed by ProfileDetailsPage, header widgets, and the address picker for cart shipping defaults.

• Metadata is a free-form map — used for client-side flags like 'has uploaded avatar this session'.
• Phone is optional — backend rejects updates that empty out a previously-set phone, so request omits the field entirely.

The cutomser_details_model.dart filename is a typo — kept as-is to avoid breaking imports.
