A python node's params reach process() as whatever its author put there,
but there was no way to put anything there: the settings form is built
from a type's declared schema, and a function node declares none.
Node types now say whether they take settings beyond their schema, and
the panel offers a key/value editor for the ones that do — named, typed
as text, number, on/off or JSON, and laid out like the port list beside
it. Rows are keyed by position rather than by name, so renaming a setting
does not remount the row and lose what was being typed into it.
Verified in the running app in both themes.
