Fix: Update deprecated APIs and dependencies

## Fix: Update Space to work with current Gradio/dependencies

This PR fixes the following issues preventing the Space from running:

- Removed deprecated `concurrency_count` from `.queue()`
- Removed incompatible pinned `httpx==0.23.0`
- Removed outdated pinned `gradio==3.34.0`

### Details
The Space is currently showing as `BUILD_ERROR`. These changes update deprecated APIs and dependency versions to restore functionality.
