feat(1099): add Payee1099Service recipient CRUD with TIN protection

Implement IPayee1099Service and Payee1099Service: list/get/create/update/ soft-delete and RevealTin. TIN is encrypted via ITinProtector on write; TinLast4 is the only clear-text fragment stored. Null Tin on update preserves the existing ciphertext. Four xUnit tests cover encrypt-on-create, null-tin-keeps-ciphertext, list-masks-to-last4, and soft-delete hides from list.
