feat(whatsapp): Convert outgoing images to JPEG before sending

Browse Source 
All images sent via the Baileys integration are now pre-processed and converted to JPEG format using the `sharp` library. This ensures better compatibility and prevents potential issues with unsupported formats.

- Images from URLs are now downloaded via axios before processing, which allows for the use of a proxy.
- The default filename and mimetype are updated to `image.jpg` and `image/jpeg` to reflect the conversion.
