Build dashboards you can actually look at and press

Widgets bind to a message name and read it live off the socket the editor
already had — lifted out of the flow editor so a dashboard route gets the
same values, which also gives the home page live data for free.

The input widgets close the loop the other way: a slider publishes into
the graph and whatever consumes that message runs. Verified end to end in
the running app — moving a slider set a flow input, and the stat bound to
what the flow computed from it followed.

View mode is plain CSS grid. A wall panel that only displays should not
download the code that lets someone drag things around, and it now does
not. Editing is a widget picker, a per-widget width control and a
settings card fed by the message catalog.

No new dependencies: the slider is a range input, the gauge is an arc,
and the markdown is a five-line subset. Charts are the one widget still
missing — they need a charting library and the chart tokens the design
guidelines reserved — so they are stored and validated but not offered.
