Merge branch 'feature/edit-recipe-event-bus' into 'master'

Feature/edit recipe event bus

## fix: feature edit recipe

**Context**

Current recipe editor is unusable in branch `master` as the recipe is unchanged after trying to edit.

**Changes**

- Change recipe parts into `EventBus` to avoid using global store (aka `Writable`) for sending recipe-related events
  * This prevent the miss timing as the event may be slower or faster than interactions
- Change ADB to be single connection pool
- Change logging from `console.*` to `logger.*`
- Add remote shell request from server.

See merge request Pakin/supra-app!4
