[Admin] Fix Unclosed form_tag in table component

[swamp09]

Summary

This PR fixes an HTML structure break caused by an unclosed form_tag, ensuring that forms added after using ui/table are rendered correctly.

Background

While customizing the index page to add a new form, I encountered a problem where the added form was not displayed in the browser. Upon investigation, I discovered that the issue stemmed from the form_tag in ui/table/component.html.erb not being explicitly closed, which resulted in subsequent form tags disappearing.

<%= render component("ui/table/toolbar").new("data-#{stimulus_id}-target": "batchToolbar", role: "toolbar", "aria-label": t(".batch_actions"), hidden: true) do %>
  <%= form_tag '', id: batch_actions_form_id %>
  <% @data.batch_actions.each do |batch_action| %>
    <%= render_batch_action_button(batch_action) %>
  <% end %>
<% end %>

Due to the lack of a proper block structure closing the form_tag, the HTML became malformed, and any form tags declared afterward were not rendered.

Updated the form_tag to use a block form, ensuring that the opening and closing tags are explicitly defined.
