feat(mini-player): the show canvas toggle, like the now playing panel

[InstaZDLL]

The mini-player plays the Canvas since #724 but had no way to hide it: the Show Canvas toggle only existed in the immersive view and the Now Playing panel.

• Same CanvasToggleButton, in the mini-player's top bar, shown under the same condition (the track has a clip, motion is not reduced), so it is never a dead control.
• The preference is shared: flipping it here also flips it in the main window, through the storage listener feat: finer spectrum, estimated karaoke, clips in the mini-player, artists to split #724 added to useCanvasEnabled.
• ui.md lists the third surface.

Checks: bun run typecheck, eslint, prettier, local review clean. Frontend only — nothing on the Rust side.
