Potential fix for code scanning alert no. 5: Full server-side request forgery

[Josh-XT]

Potential fix for https://github.com/DevXT-LLC/ezlocalai/security/code-scanning/5

To fix the problem, we need to ensure that the audio_url is validated before being used in the requests.get call. One way to do this is to check that the URL belongs to a trusted domain. This can be done by parsing the URL and verifying its components.

1. Parse the audio_url to extract its components.
2. Validate that the URL belongs to a trusted domain.
3. If the URL is valid, proceed with the requests.get call; otherwise, handle the invalid URL appropriately.
