Integrate Postman Collections and Environments from File System

[aphanor-postman]

Summary

This PR sets up integration between this repository and the linked Postman workspace.

The following assets are introduced:

• postman/ — Contains exported contents of the linked Postman workspace (collections, environments, APIs, etc.)
• .config/ — Stores workspace configuration required for synchronization
• .github/workflows/postman-publish.yaml — GitHub Actions workflow to keep repository files in sync with Postman Cloud

What this enables

The postman-publish.yaml workflow ensures that changes made locally to the Postman files are automatically synchronized with the linked Postman workspace in Postman Cloud.

This establishes GitHub as the source of truth while keeping the Postman workspace continuously up to date.
