Subject: [PATCH] feat(studio): optimize mobile user experience

- TopBar: responsive layout with mobile hamburger menu, hide non-essential elements on small screens
- TopBar: show only current page breadcrumb on mobile, full navigation on desktop
- TopBar: improved spacing and touch targets (px-2 on mobile, px-4 on desktop)
- TopBar: hide theme toggle, mode badge, and API badge on mobile for cleaner UI
- ObjectDataTable: add useIsMobile hook import for future card view implementation
- Improved mobile navigation with SidebarTrigger button (44px touch target)

Addresses Priority 1 & 2 from mobile UX optimization plan
