 * Normalize form state by converting objects with numeric string keys to arrays.
 * TanStack Form sometimes creates { "0": value, "1": value } instead of [value, value]
 * when using indexed field paths like "parent.0.child".
 *
 * This function also handles the variant cleanup case where objects have mixed
 * numeric and named keys (e.g., { "0": old, "Add": current }) by removing
 * orphaned numeric keys.
 *
 * This function recursively processes the form state and fixes these issues.
