chore(sidekiq): log ActiveJob class and job_id on dequeue (#12704)

## Context

Sidekiq logs only showed the Sidekiq wrapper class and JID, which wasn’t
helpful when debugging ActiveJobs.

## Changes

- Updated `ChatwootDequeuedLogger` to log the actual `ActiveJob class`
and `job_id` instead of the generic Sidekiq wrapper and JID.

> Example
> ```
> Dequeued ActionMailer::MailDeliveryJob
123e4567-e89b-12d3-a456-426614174000 from default
> ```

- Remove sidekiq worker and unify everything to `ActiveJob`
