pco-plan: display settings are per tile again (gear menu), admin keeps the connection

Top bar (template, item-type tint, key color) and the whole show/hide
checklist move from admin config to instanceSchema, grouped in the gear
popover ("Top bar" open, "Show / hide" folded, three columns). They are
browser-side choices stored with the layout, not server state. Admin now
holds only credentials, service type, plan, poll interval and the
ProPresenter follow switch. noteCategories moves to the tile too.
