refactor(api): buses only in services, atomic commands, @Prop schemas

- Mongo read models are @Schema/@Prop classes (SchemaFactory), still
  loose: the props declared are the indexed or shaped ones.
- CommandBus and QueryBus are used by the application services alone.
  Duplicating a ticket, bulk updates, CSV imports, proposals and
  emptying the trash chain several commands, so they are service
  methods now and their composite commands are gone; every command
  handler is atomic. No forwardRef is needed.
- The due-date and trash timers are entry points: they live in the
  presenters and call the services. The automations event handler has
  its own file and calls AutomationsService.
- The tracker's user directory asks IdentityService; the composition
  root hands the identity application module to the tracker
  infrastructure (withIdentity), with no global module.

-- `presenters` nunca importa `infrastructure` ni usa los buses CQRS: habla con los `*.service.ts` (API) o con las facades (web).
+- Los buses CQRS (`CommandBus`, `QueryBus`) solo los usan los `*.service.ts` de `application`; todo lo demás pasa por
+  un servicio: resolvers, controllers, temporizadores (recordatorios, papelera; por eso viven en `presenters`), el
+  handler de eventos de las automatizaciones y el directorio de usuarios del tracker (`IdentityService`). La única
+  excepción es el `EventsBridge`, que ejecuta los comandos que devuelven las sagas.
+- Los comandos son atómicos: un handler no ejecuta otros comandos. Lo que encadena varios (duplicar un ticket, la
+  edición en bloque, importar un CSV, las propuestas, vaciar la papelera) es un método del servicio, que ejecuta los
+  comandos uno a uno con su bus. Así no hay ciclos entre servicios y handlers, ni `forwardRef`.
+- Sin módulos globales entre contextos: el tracker recibe el módulo de aplicación de identidad en la raíz de composición

+- `presenters` nunca importa `infrastructure`: habla con los `*.service.ts` (API) o con las facades (web).
 - `infrastructure` nunca importa `presenters`.
 - Los contextos también están acotados: `tracker` puede usar `identity` y `shared`; `shared` no depende de nadie; la web
   no depende de la API (y viceversa).
