Data tab in the diagnostics panel

A new Data tab gives you a clear, read-only view of every collection your app uses. It shows an access matrix with Owner, Member, and Anonymous visitor columns — so you can see at a glance who can read and write what, plus row counts per environment. Data is now the default tab when you open diagnostics, since it's the best place to start understanding how your app behaves. A short footnote reminds you that the matrix reflects storage rules; apps often add extra UI gates on top.
