VSN-1977 : Preparing similar normalized passenger hooks in the context of prepared passengers to be used later on in both optimisations of UI and Integration logics.

Preparation Module Normalization and Prepared-Normalized Mapping Logic.

1. Introducing Duplicated Files

• Added duplicated reserve files to support upcoming optimization logic.
• Prepared test data to compare and optimize processing of similar Passenger DTOs.

---

2. Adding Normalized Passengers

• Defined a hook to be customized during prepared passengers retrieval.
• Introduced the normalizedPassengers variable within the preparation store to support future optimization workflows.

---

3. New Hook Introduction

• Added a new hook inspired by the normalized passenger hook as an initial trial for upcoming optimization logic.
• Defined a new mapping between the Prepared Passenger DTO and the Normalized Passenger DTO to support enhanced processing.

---

4. Applying Mapping in Store

• Integrated the Prepared-to-Normalized mapping directly into the API call workflow.
• Ensured that normalized data is used seamlessly within the preparation store.
