fix: save and display professional profile address, payment methods, and docs

- DTO: add payment_methods field so whitelist pipe no longer strips it
- Service upsert(): extract payment_methods and write as Prisma nested upsert instead of passing flat object
- Admin detail page: fix image regex to handle Firebase URLs with query params; fix payment_methods display for 1:1 Prisma relation (object, not array)
