Lead the files browser's folders with a tinted type icon

Each folder row in /admin/files now opens with its type as an icon in a
box tinted with its own hue (Bots ember, Workspaces teal, Computers
cobalt, Media violet, MCP servers moss, Database amber), so the picker
reads at a glance and the row's width goes to the name. The box carries
the type as its title, so hovering still names it.
