Website service target setup (#2)

This PR contains the work done to add and setup the *Website* service target, a **Hummingbird** server app, into the Xcode project as a SwiftPM package with full support for containerization and driven by a `Makefile` file.

To provide further details about the work done:

* Swift package — SwiftPM manifest with a Website executable, related library, and test targets; depends on **hummingbird** and **swift-configuration**.
* Containerization — Multi-stage `Dockerfile` producing a static-linked release build with jemalloc, running as a non-root user on port 8080. Production and local-dev `docker-compose` files included.
* Configuration — `.env.local` template (with `.env` git-ignored) and `.dockerignore`/`.gitignore` entries.
* Makefile — Self-documenting operational commands:
  * pkg — SwiftPM: _build, release, test, clean, reset, deps, outdated, update_
  * img — Docker lifecycle: _build, mount, unmount, release_

Notes

* New service only — no changes to existing code; nothing else in the repo is affected.
* App logic is currently scaffolding; this PR establishes the service structure, build, and deployment tooling.
