apply-new-account / apply-remove-account / apply-toggle-amount-mode rebuilt the account
rows from the decoded :snapshot, dropping any value the user typed but that had not yet
round-tripped into the snapshot (type 50%, click "New account" -> first row reverts,
giving a 66.67/33.33 split instead of 50/50). Read the live :step-params rows instead
(already schema-decoded by mm/wrap-wizard, so typed), falling back to snapshot only when
absent. First stage of removing the snapshot round-trip; fixes a real user-facing bug
(typed amounts lost on add/remove/$%-toggle).
Restore the percentage-split e2e to the realistic type-then-add ordering as a regression
guard. Modal stays green: swap 6/6, transaction-edit 8/8.
