🔄 chore: Consolidate agent model imports across middleware and tests from rebase

- Updated imports for `createAgent` and `getAgent` to streamline access from a unified `~/models` path.
- Enhanced test files to reflect the new import structure, ensuring consistency and maintainability across the codebase.
- Improved clarity by removing redundant imports and aligning with the latest model updates.
