feat: logos_delivery_node app + messaging REST API with event observability (#4014)
* WIP logosdeliverynode app initial commit

* WIP - extra cli option

* WIP: messaging client REST endpoints

* Add event poll for messaging rest with cache mechanism

* Messaging rest tests

* test: assert 404 via raw string client in messaging REST test

presto's typed REST client raises RestDecodingError when it cannot decode
a non-2xx text error body into the response type. Add a RestResponse[string]
stub (messagingGetSendEventsByIdRawV1) and point the "already-polled id ->
404" assertion at it, matching the relay REST test pattern.

* remove customized cli args as confutils has no support for it

* Introduce --entry-layer and re-introduce --mode flags into cli args, applied new driver into LogosDelivery + tests

* Add messaging REST client test

* Add docker image build of logosdeliverynode for CI builds

* Fix tests

* Potential fix for pull request finding

* Refactor Messaging REST API to better match Messaging Send and Receive APIs

* chore: migrate messaging REST API to Opt[T]

Follow-up to the rebase onto master's repo-wide Option[T] -> Opt[T] change
(#4035). Converts the code this branch adds to the new convention:

- messaging/rest_api/types.nim: MessagingJsonEnvelope fields to Opt[T],
  Opt.some/Opt.none, and json_serialization/pkg/results instead of
  json_serialization/std/options.
- tests: WakuNodeConf.clusterId is now Opt[uint16]; DTO fields are Opt.

`Option[ContentBody]` in the handlers is presto's own API and stays as-is.
