Add go-nanoid dependency and refactor user provider methods

- Added the go-nanoid library for generating unique IDs, enhancing user ID management.
- Refactored user provider methods to improve clarity and consistency, including updates to user retrieval and authentication processes.
- Adjusted user model fields to align with new ID generation strategy, ensuring compliance with best practices.
- Cleaned up code by removing obsolete test files and improving overall structure for better maintainability.
