chrome dropout improved media controls extension

Hello, because of recent chrome extensions block, I switched to Firefox. I found cool media controls extension and I vibe-coded some improvements on top of it. The original one is from Tony Chan. Both are open source: Tony's, mine.

new features:

• share button which generates qr code to scan and/or paste url (for PictureInPicture or cast feature from other apps)
• live badge for stream media + limited controls (forward, backward, loop excluded)
• loop current media button
• volume slider with mouse scroll support
• improved thumbnail fetch for Spotify, Twitch and SoundCloud
• slight UI redesign
• Spotify support (a bit buggy)
• options page: hide thumbnails, set media duration for live media
• keyboard shortcut to open extension and mute all media
