Add hotkey and button for layer visibility

[hipsterusername]

A new feature was implemented to show/hide all non-raster layer categories in Canvas Layers.

• A new Redux action, allNonRasterLayersIsHiddenToggled, was added to canvasSlice.ts. This action toggles the visibility of Control Layers, Inpaint Masks, and Regional Guidance. The logic ensures that if any non-raster layer is visible, all are hidden; if all are hidden, all are shown. Raster layers remain unaffected.
• A new hook, useNonRasterLayersIsHidden.ts, was created to derive the current hidden state of all non-raster layers, informing UI elements.
• A new component, CanvasNonRasterLayersIsHiddenToggle.tsx, was introduced. This component provides a button that visually indicates the hidden state (eye open/closed) and dispatches the toggle action on click.
• The CanvasNonRasterLayersIsHiddenToggle button was integrated into EntityListSelectedEntityActionBar.tsx for easy access within the Canvas Layers panel.
• A new hotkey hook, useCanvasToggleNonRasterLayersHotkey.ts, was implemented and integrated into CanvasLayersPanelContent.tsx. This registers Shift+H as a hotkey in useHotkeyData.ts to trigger the allNonRasterLayersIsHiddenToggled action, providing a quick keyboard shortcut.
• New translation strings were added to en.json for the hotkey documentation and button tooltips.
