♻️ (pagetop): Migra de actix-web a Axum

Sustituye el módulo `service` por `web` y adapta toda la API al modelo
de Axum: router inmutable, extractores via `FromRequestParts` y
servicios Tower para archivos estáticos.

- `HttpRequest` pasa a ser un tipo propio, mínimo y clonable.
- `configure_services` pasa a `configure_routes`.
- `EmbeddedFilesService` pasa a `ServeEmbedded`.
- Elimina `session_lifetime` de `Server` (va a `pagetop-auth`).
- Actualiza tests y ejemplos a la nueva API.
