ui.pointer, ui.click/ui.move, ui.key and ui.screenshot read every value
with as_f64/as_bool/as_str and fell back to a default on any other type,
and an unknown button or event kind fell through to a left click or a
move. A typo such as "button":"ritgh" ran a different action and still
replied ok.
Each method now validates its whole request before acting, like ui.set:
unknown fields (top-level, under modifiers, or in an event), wrong JSON
types, unknown button/kind/tool values (the error lists the accepted
ones) and out-of-range pressure, tilt and rotation return an error that
names the parameter, and nothing is queued or applied. Null fields still
mean omitted, and valid calls behave as before.
