PR Summary

Data Model Refactoring: Entry to Server Type Transition

Overview

This PR implements a fundamental data model restructuring, replacing the Entry type with Server type throughout the codebase, including database interfaces, service layers, and core model definitions.

Change Types

Type	Description
Refactor	Major restructuring of Go API schema definitions
Breaking	Complete modification of data model hierarchy and service interfaces

---

Affected Modules

Module / File	Change Description
database/mongo.go	Changed the type of 'results' variable from []*model.Entry to []*model.Server in MongoDB List function
model/model.go	Complete overhaul of schema definitions including removal of struct types, addition of new ones, and transition from JSON-only to JSON+BSON tags
service/fake_service.go	Changed return type of fakeRegistryService.List method from []model.Entry to []model.Server

---

Breaking Changes

• All code depending on model.Entry type will need to be updated to use model.Server
• Data model hierarchy has been significantly altered
• Service interfaces now return different types
• Database operations now work with different data structures

---

Notes for Reviewers

• Verify that all references to the old data types have been updated consistently
• Check for any potential data migration concerns with the schema changes
• Ensure BSON tags are properly aligned with existing MongoDB collections
