web: regenerate types and sync for the new forwarding levers

go generate brings novelty, harmAwareness, programEffect into the
generated Config and Bounds; preset base, field labels, the clamp switch,
and the test fixtures pick them up. No UI for them yet (that is the next
slice); behaviour and the demo are unchanged. type-check, unit tests and
lint all green, so CI's type-drift guard is satisfied.
