The marketplace send tab (17.tpl) was refactored with an empty <script>
block, which dropped the `haendler` (available merchants) and `carry`
(per-merchant capacity) globals that add_res()/upd_res() in unx.js rely on.
Without them `ic = haendler * carry` evaluates to NaN, so clicking the
"(capacity)" link next to a resource (or the resource icon) no longer fills
the input. Restore the two globals so the max-per-merchant fill works again.
