Opening a node or the flow settings now takes the flowbar and the dock
away, leaving the graph and the panel; they come back on close, leaving
by the same slideUp they arrive with. The panel header names the flow
before the node, `/heating/`, which is how messages are qualified
everywhere else.
Opening a flow already fitted, and pressing Fit to screen, disagreed:
one used a 0.25 padding capped at 1x, the other xyflow's defaults, so
the button visibly jumped and a small flow opened at 100% in an empty
canvas. Both read one constant now.
