Added new routes to the `ReverseProxy` configuration, including
`receiver-ui-login`, `receiver-ui-sender`, `receiver-ui-envelope`,
and others to handle specific paths, HTTP methods, and transformations.
Removed outdated routes such as `receiver-ui-static-assets` and
`receiver-ui-annotation-fake` to streamline the configuration.
Introduced transformations for response headers (e.g., `Cache-Control`)
and updated `auth-login` and `auth-envelope-receiver-login` routes
with new path patterns and query parameters.
Reorganized `receiver-ui` cluster routes to better handle static
assets (CSS, JS, Blazor framework, and content) and fake data.
