App mode support; hide ComfyUI's Workflows and Apps tabs

Live edits keep each person's graph/App view, cursors are off in the App
view, and .app.json workflows show as apps in Files, the Live list and Save.
ComfyUI's own file tabs duplicate Files, so they are hidden by default (admin
setting hide_comfy_file_tabs) and their shortcuts open Files.

+ComfyUI's own **Workflows** and **Apps** tabs are hidden, since Files replaces them, and their keyboard shortcuts open Files. Admins can bring them back under *Admin → Server settings*. Hiding them isn't what protects the files, though: the server applies the same rules whichever browser is used. If you show ComfyUI's open workflow tabs in the sidebar (*Comfy.Workflow.WorkflowTabsPosition*), the Workflows tab stays, because it lists them.

 Click a workflow to open it. The Files tab marks live workflows with a green dot. **From computer** opens a workflow file from your machine, like ComfyUI's own *Open*.
 
 Hover a row for its actions: **Rename**, **Move to…**, **Delete**, and on a shared folder you own, 🔒 **Who can open it**. The folder button creates a folder. In the Shared tab it creates a shared folder that you own.
