Update Folder Structure for Network Participant (NP) Logs

**Issue Details:**

#### Problem Statement:
The current folder structure lacks organization for Network Participant's implemented examples, making it challenging to manage and locate specific workflows implemented by NPs.

#### Proposed Solution:
Update the folder structure to include a dedicated "NP Logs" directory, with subdirectories for each Network Participant. Each NP directory should contain subdirectories for specific workflows (e.g., search, select).

#### Benefits:
- Improved organization and clarity for NP examples.
- Simplified navigation and maintenance of NP-related workflows.
- **Improved Collaboration:** Any new Network Participant (NP) joining the project will have ready-made references available on how other NPs have implemented specific use cases.
- **Enhanced Documentation:** Documenting the logs will contribute to better spec governance, compliance, and transparency. It will also serve as a valuable resource for building test cases for Network Validation.
- **Knowledge Transfer and Training**: The documented logs can be utilized for training AI models in the future, aiding in the generation of use-case-specific JSONs. This promotes knowledge transfer and ensures a valuable resource for future development.

**Additional Information:**
- Consideration for future NPs can be made by creating subdirectories accordingly.
- Ensure backward compatibility with existing examples during the migration.
