[Feature] Identify and Highlight Video Links with Play Icon

[sakethpathike]

Is your feature request related to a problem? Please describe.
This was suggested by Kizuryuu-nosuuke on Discord. While not a problem, it would improve usability. For media links in video format (such as video posts shared from Tumblr), there’s no quick way to identify or play the video directly.

Describe the solution you'd like
A small play icon next to the thumbnail or link for video-format media. This would make it easier to identify and play videos quickly.

Describe alternatives you've considered
Currently, manually open the link to check if it’s a video.

Additional context
Adding a play icon would improve the user experience by making video media links more recognizable and accessible.
