This PR contains the work done to introduce server-side localization support to the **Website** service so the landing and error pages are served in the visitor's negotiated language, backed by a new reusable Localization package. To provide further details about the work: * Created the _Localization_ package — a bundle-bound `Localize` method and a `LanguageList` type. * Language negotiation — `NegotiateLanguage` method picks the best supported language from the request's _Accept-Language_ header (falling back to the default); the `LocalizationMiddleware` middleware resolves it per request and stores it on a new `LocalizedRequestContext` / `WebsiteRequestContext` context. * Localized responses — `LocalizedHTMLCollectionResponse` pre-renders each page once per language and caches the bytes (with `Content-Language` + `Vary: Accept-Language`), reused by the `RootController` controller and `NotFoundMiddleware` middleware. * The `CachedHTMLResponse` response gained custom-header support. * Localized pages — the `IndexPage` and `ErrorPage` pages now resolve their strings via `Localize` method; * Added `Localizable.xcstrings` catalogs. * Wired the `LocalizationMiddleware` middlewaer into the router.
