Move domain packages into a new modules.* hierarchy and rename controller packages to api.* across login, registration, and user modules. Update package declarations and imports (including shared.api DTOs and JwtService -> modules login TokenGenerator), adjust tests and persistence/mapper paths accordingly, and apply minor formatting fixes (missing EOF newlines). This reorganizes the project to better separate API surface and module boundaries.
