fix(core): Handle max stalled count error better

[ivov]

Summary

The max stalled count error is not being wrapped correctly and could use with clearer phrasing.

Context: https://n8nio.slack.com/archives/C035KBDA917/p1737657316221569

To test:

1. Clear all bull keys: docker exec -it n8n-redis redis-cli EVAL "redis.call('DEL', unpack(redis.call('KEYS', 'bull:*')))" 0
2. Comment out this line and build: await this.recoveryService.recoverFromLogs(executionId, logMesssages ?? [])
3. Start a main and two workers
4. Activate a workflow with a webhook and an OOM debug helper, call the webhook
5. Worker will pick up job and crash, other worker same, main surfaces clear max stalled count error
