Bluesky Better Video wot David Casanova

This is a FIX for devices that dont show the volume slider, a solutions is WIP in GitHub (https://github.com/bluesky-social/social-app/pull/5919)

Save your desired volume and unmute videos automatically when hovering over them, once you hover video is unmuted until you scroll and hide the video.

Version 1.0
- Hides Bluesky's video controls
- Shows native video controls (browser-based)
- Stores video volume set by user and applies it to all videos
- Unmutes when mouse is moved over the video so you can watch videos in feed without unmuting each video.

There are no screenshots that show how the extension works, it just does, watch the video preview.
