Potential fix for https://github.com/Coder-Vippro/ChatGPT-Discord-Bot/security/code-scanning/7

The correct fix is to parse the URL and ensure the hostname portion matches the allowlist of image hosts (cdn.discordapp.com, etc.), rather than just checking for a substring presence anywhere in the URL. This should be performed using urllib.parse.urlparse to extract the hostname and compare it directly or using .lower().endswith() for subdomain/general matching.

Specifically, edit line 844 (and any similar logic for media.discordapp.net) in src/utils/image_utils.py within the _download_image method to parse the URL and check its hostname against the image hosts. This may require importing urlparse from urllib.parse if not already present.

No other changes outside these lines are required. Do not alter existing functionality, other than securing the host match.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.
