feat: add user model and repository along with datafx provider

- Introduced `User` model with various fields such as Id, Kind, Name, Email, Phone, and timestamps.
- Defined `UserKind` constants for user roles: Admin, Editor, Regular.
- Created `UserRepository` interface with `CreateUser` and `GetUserById` methods.
- Implemented `UserRepositoryImpl`.
- Added `datafx` package with `DataProvider` interface and `DataProviderImpl` struct.
- Integrated `datafx.Module` into the main `bliss.Module`.
