Rename DIContainer to TSInjex and refactor interfaces

- Renamed DIContainer class and related references to TSInjex to better indicate its purpose as a TypeScript-based dependency injection container.
- Extracted IDependency interface to a separate file to improve modularity.
- Split the ITSInjex interface into ITSInjexRegister and ITSInjexResolve, then extended them in a new ITSInjex interface to clarify the separation of concerns.
- Updated tests and decorators to reflect the renaming and interface changes.
- Adjusted helper, functions, and index export to align with the new TSInjex structure.
