Admin: a module card is a status line until you open it

Every module's settings were always spread out, so the page read as a wall
of forms. A card now shows what you check at a glance — dot, name, version,
description, status readout, the enabled switch, Uninstall — with one button
at the bottom right: Configure opens the settings and becomes Apply, which
saves without closing them. Clicking the module name opens and closes the
settings too (keyboard as well: it is a focusable button). A card stays open
across a reload for the rest of the session, so re-checking something after
an Apply doesn't fold it away. A module with nothing to configure has no
button.
