Modal that lets the user pick a sort strategy for a bulk reorder.

Wraps core's <.modal> and renders radio buttons for each strategy the consumer LV passes in. The scope label tells the user up front whether the apply will rewrite "all N rows" or "the M selected rows" so they see the consequence before clicking Apply.

Strategies are domain-specific (projects sort by name, tasks by title, ai endpoints by priority, etc.) so the consumer owns the strategy list — the modal is just shell + radio UI.

Example

<.reorder_modal
  show={@show_reorder}
  on_close="close_reorder"
  on_apply="apply_reorder"
  selected_count={length(@captured_uuids)}
  total_count={length(@projects)}
  strategies={[
    {"name_asc", gettext("A → Z by name")},
    {"name_desc", gettext("Z → A by name")},
    {"created_desc", gettext("Newest first")},
    {"created_asc", gettext("Oldest first")},
    {"reverse", gettext("Reverse current order")}
  ]}
  noun_singular={gettext("project")}
  noun_plural={gettext("projects")}
/>

The Apply button submits the form, which emits on_apply with %{"strategy" => <value>} — value is the first element of each {value, label} tuple. required on the radios blocks empty submits at the browser level; the consumer LV should still guard against bad strategy strings server-side (whitelist + fallback clause).
