Adds NLE-style hotkeys for muting audio and toggling loop playback in the Studio player, matching the workflow conventions in DaVinci Resolve, Premiere, and Final Cut. - M toggles audio mute (no-op above 1x playback, matching the mute button's existing gating behavior). - Shift+L toggles loop. Ctrl/Cmd+L was considered but is filtered out by shouldIgnorePlaybackShortcutEvent and conflicts with the browser address bar; Shift+L is also consistent with the existing Shift+I / Shift+O modifier pattern. The Shift+L handler runs before the existing plain-L shuttle case so it doesn't also start forward playback. Fixes #905
