feat(player): copy video link button

User request (07-10): a quick way to grab the direct video URL to share or open
elsewhere. Added a link icon in the player top bar that copies the current playing
URL to the clipboard (direct CDN URL for most sources, so it pastes into VLC/MX/a
browser; proxy-wrapped/referer-bound sources are best-effort).
