Appserver Microservices: first iteration

[this-Aditya]

Summary

This PR contains the first iteration of migrating Appserver from a monolith to a microservices architecture.

What this PR adds

This change introduces the initial microservices modules and the gateway used to route requests:

• microservices/core — Common business logic, shared entities/DTOs, and core utilities reused by services (ported from appserver-jersey).
• microservices/contract — Client-side contracts and helpers for inter-service HTTP calls.
• gateway-service — Single public entry point that routes requests and applies JAX-RS authentication/authorization filters.
• microservices/project-service — Initial project domain service.
• microservices/github-service — Service responsible for fetching GitHub content.
• microservices/protocol-service — Service providing protocol retrieval endpoints.

Note

• This is an early phase implementation and does not yet contain a complete, runnable Appserver. It provides initial service implementations.
• The code and module are subject to change as further phases of the migration progress.
• Follow-up work will focus on completing service implementations
