fix(ssr): transaction rule wizard drops fields on Next

The EditModal step body wrapped all rule fields in a nested
<form id="my-form"> inside the wizard's own #wizard-form. By HTML
form-ownership rules those fields belonged to the inner form, so when
htmx serialized #wizard-form on Next, none of the step-params fields
were sent. The server saw an empty rule, reported "required" for
description/accounts, and re-rendered a blank wizard (losing input).

Replace the nested <form> with a plain <div>; the wizard form already
owns submission, so the inner form and its htmx attributes were
redundant.
