chore(event-bus, workflow-engine): Enable more granualar queues configuration (#14201)

Summary

  This PR adds BullMQ queue and worker configuration options to the workflow-engine-redis module, bringing feature parity with the event-bus-redis module. It also introduces per-queue
  configuration options for fine-grained control over the three internal queues (main, job, and cleaner).

  Key changes:
  - Added per-queue BullMQ configuration options (mainQueueOptions, jobQueueOptions, cleanerQueueOptions and their worker counterparts) with shared defaults
  - Unified Redis option naming across modules: deprecated url → redisUrl, options → redisOptions (with backward compatibility)
  - Moved configuration resolution to the loader and registered options in the DI container
  - Added comprehensive JSDoc documentation for all configuration options
  - Added unit tests for option merging and queue/worker configuration

  Configuration Example

```ts
  // Simple configuration - same options for all queues
  {
    redisUrl: "redis://localhost:6379",
    queueOptions: { defaultJobOptions: { removeOnComplete: 1000 } },
    workerOptions: { concurrency: 10 }
  }
```

```ts
  // Advanced configuration - per-queue overrides
  {
    redisUrl: "redis://localhost:6379",
    workerOptions: { concurrency: 10 },        // shared default
    jobWorkerOptions: { concurrency: 5 },      // override for scheduled workflows
    cleanerWorkerOptions: { concurrency: 1 }   // override for cleanup (low priority)
  }
```
