chore(bus): prune stale dequeue result type

[yordis]

• The old dequeue result shape no longer has a consumer after queue routing moved to message synchronization groups.
• Keeping the orphaned type makes the bus surface look broader than it is.

PR Summary

Low Risk
Low risk cleanup that deletes an unused bus DTO/struct; main risk is only for downstream code that might still reference the type.

Overview
Removes the unused QueueBatchDequeueResult struct (QueueBatchDequeueResult.cs), pruning a stale part of the bus surface that no longer has any in-repo references.

Poem

A struct once held the queue's sweet count,
But now it fades without a doubt,
The dequeue dance must find new ways,
As we hop through cleaner days! 🐰✨
