Refactor token management, client initialization, and project handling

- Consolidated `TokenStorage` struct into `internal/auth/models.go` for better organization.
- Updated `Client` to use `TokenStorage` for managing email and project ID.
- Simplified `SetupUser` method to ensure proper token and project assignment.
- Refactored API handlers to leverage new `GetEmail` and `GetProjectID` methods in `Client`.
- Cleanup: Removed unused structures and redundant code from `client.go` and `auth.go`.
- Adjusted CLI flow in `login.go` and `run.go` for streamlined user onboarding.
