feat(web): mobile top bar with tabs, chat toggle, and home sidebar sheet

[rafavalls]

What is this contribution about?

Adds a mobile top bar to the agent shell that surfaces the main-panel tabs bar plus chat-toggle and new-task buttons alongside the existing menu button, and conditionally renders MainPanelContent (wrapped in ErrorBoundary + Suspense) when mainOpen is true on mobile so users can switch between chat and main panel views. Adds a mobile home toolbar to org-shell-layout with a sidebar sheet that mounts StudioSidebarMobile + TasksPanel, and removes outer padding/border-radius from org-home on mobile for a full-bleed layout. Drops a no-op ml-auto from MainPanelTabsBar so it composes correctly inside the new mobile container.

How to Test

1. Open the app on a mobile viewport (or narrow window) and navigate to an org route — confirm the new mobile home toolbar shows a menu button that opens the sidebar + tasks panel sheet.
2. Open a task — confirm the mobile top bar shows the menu, scrollable tabs bar, chat toggle, and new-task button; toggling chat swaps between chat and main panel content; tapping a tab switches to the corresponding main-panel view.
3. On desktop, confirm the toolbar tabs and home layout are unchanged.
