Fold the slot and app tables away instead of one long page

Sixteen app rows (most of them empty or holding something that is not an app) plus five slot rows made the column long enough to be annoying, so each table is now a details pane: the firmware slots start open, the app list starts folded, and the state that used to sit in its own row moved into the summary line. Same ids, so loadSlots and loadApps are untouched. A front-end test asserts both panes exist and that the app list starts folded.
