ComfyUI deployment on FIPS linux systems - Fatal Error

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I expect to be able to run the process, or the contain on a FIPS enabled system.

### Actual Behavior

The process fails to initialize.

### Steps to Reproduce

Get a FIPS enabled system, try to run ComfyUI via python or a container.

### Debug Logs

```powershell
fips.c(145): OpenSSL internal error, assertion failed: FATAL FIPS SELFTEST FAILURE
```

### Other

The solution here is quite simple. the python package AV has made a change in their 15.X version that is causing these deployments to fail. Simple change the AV line to the specific version of 14.4.0:
https://github.com/comfyanonymous/ComfyUI/blob/master/requirements.txt

Change
```
av>=14.2.0
```

to:
```
av==14.4.0
```

Start with requirements.txt and reproduce the reported startup failure on a FIPS-enabled Linux system, checking the av dependency constraint. Done means ComfyUI initializes under FIPS when launched through Python and in the container, with the dependency installation verified.
