room settings button: room-centred, icon-sized, zooms with the plan

Owner's spec: the button is no longer glued to the room NAME (which the user
can drag anywhere) — it anchors to the geometric centre of the ROOM
(interiorPoint for polygons, so an L-shaped room gets a point actually
inside it), one button-height below centre so it never covers the name,
whose default position is that same centre. Height is 70% of a device icon
box, and since --icon-size already rescales with the view, the button zooms
with the plan instead of keeping a constant screen size (verified: x2.2 zoom
-> x2.20 button). The small metric rows under the room name (temperature,
humidity, signal, lights) now render in the plan editor too — they used to
be view-mode only.

smoke_room_cards updated: plainInPlan now asserts metrics ARE present in the
editor (the old assertion pinned the old behaviour), plus gearDetached.
