YouTube URL Enhancements and Video Verification after Download

[movchan74]

Summary:
This Pull Request enhances our YouTube integration by allowing more complex URL parameters and improving error handling for invalid video content.

Key Changes:

1. Extended URL Parameter Support: Now supports additional parameters in YouTube URLs, such as 't=4s&ab_channel=A24'. Currently, the extra parameters are ignored, we will add proper support for the video start time parameter later.
2. Improved Error Handling for Invalid Videos: Added video-checking post-download. If the downloaded content is not a valid video, the system now raises a VideoReadingError, ensuring that only valid video content is processed and error messages are more meaningful.

Good but let's not use regex for parsing URLs

@evanderiel I removed VideoSource in favor of using yt-dlp for all video downloads. Please, take a look again.

Just a question about the video downloader
If the video is not exist or the url is not valid, does it creates a empty file or throw exception. If possible we can use different error message in the UI.

@HRashidi If it cannot download the video, it will throw DeownloadException and nothing will be saved.

Looks good, but please fix the usedforsecurity parameter with md5 & resolve comments before merging
