This PR contains the work done to provide optimizations to the current service, such as a health-check endpoint, pre-renders static HTML pages, and hardens the error page's CSP. To provide further details about the work: * Added the `HealthController` controller serving GET `/health` with a static JSON payload. * Added the `CachedHTMLResponse` response, which renders a static HTMLDocument to bytes once and reuses them per request (no Content-Length, so responses stay compressible). * Integrated the response into the `RootController` and the `NotFoundMiddleware` middleware to avoid re-rendering on hot paths. * Added a `RouterMethods.addRoutes(_:)` extension and switched the router in App+build to use it. * Moved the inline style from the `ErrorPage` page into a dedicated style file so the CSP needs no inline-style escape hatch. * Fixed the `IndexPage` page path inconsistencies. * Written the `README` file.
