Let a Home tile lead where its figure does, and drop the logo nobody saw

`Tile` takes an optional link: Nodes and Flows running to /flows, Runs
running to /runs, Failures down to the list further down the same page.
Queue backlog and loop lag have no screen of their own and stay plain.

`Logo`'s responsive variant carried a second `<img>` for the collapsed
rail, but AppSidebar hides the whole logo when collapsed, so an ancestor
`display: none` meant it never rendered in any state.
