feat(studio): phone editing for Video Studio + Image Editor (remove desktop gate)

Replaces the "desktop only" gate on phones with real mobile editing layouts.

Shared:
- BottomSheet (mobile slide-up panel) hosting the desktop side-docks on phones.
- Side panels made width-fluid (w-full on mobile, fixed on md+): StudioSidebarContent,
  ImageEditorRightPanel.

Video Studio (VideoStudioMobileLayout):
- Canvas fills the viewport; the vertical tool dock becomes a scrollable bottom bar;
  each tool's panel + the timeline open as bottom sheets. Exported MAIN_DOCK_ITEMS.

Image Editor (ImageEditorMobileLayout):
- Canvas fills the viewport; toolbar → scrollable bottom bar; Adjust/Filters/Layers
  panel + shape picker open as bottom sheets. Exported IMAGE_TOOLS/IMAGE_SHAPES.
- Touch editing: Stage now handles onTouchStart/Move/End (draw, select, move) with
  touch-action:none; draw-tool stroke works with a finger. Pointer handlers widened
  to MouseEvent | TouchEvent.

i18n: added timeline/preview/panels keys (fa+en, parity verified). Full next build +
tsc clean. (Studio is auth-gated — verify editing on a device.)
