Description

Fixes row action buttons disappearing after pagination (and any other Livewire
update, e.g. sort/search/filter) on Livewire 4.4.2+. The action column header
stays, but the buttons vanish from every row starting on page 2.

Root cause: in v6 the per-row actions are injected client-side.
dispatchActionsToJS() pushes the action HTML through $this->js('pgActions', …),
which the support-livewire-v4 script stores in a global window['pgActions_' + id].
Each row renders them with x-html="toHtml", and toHtml() reads that global.
Because the global is not an Alpine-reactive dependency, x-html is evaluated only
once — when Alpine initializes the morphed node. Livewire 4.4.2 ("Close asynchronous
morph timing gaps") reordered the morph so Alpine now evaluates toHtml() before
the $this->js('pgActions') effect refreshes the global. The stale global has no
entry for the new page's row ids, so toHtml() returns an empty string and the
buttons disappear.

Fix: re-render the actions once the fresh data lands, independent of the
morph / JS-effect ordering:

• support-livewire-v4.blade.php dispatches a pg:actions-updated window event
  right after refreshing window['pgActions_*'] / window['pgActionsHeader_*'].
• pgRenderActions gains a reactive renderTick counter, incremented by a
  pg:actions-updated listener (registered in init(), cleaned up in destroy()).
  toHtml() now reads renderTick, so Alpine re-evaluates the x-html binding as
  soon as the up-to-date action data is available.

Behavior is unchanged on the initial page load and on Livewire < 4.4.2 — the fix
only adds a re-render trigger that morph timing used to supply incidentally.

Example (unchanged usage, now correct across pages):

public function actions(Dish $row): array
{
    return [
        Button::add('edit')->slot('Edit')->dispatch('edit', ['rowId' => $row->id]),
        Button::add('delete')->slot('Delete')->dispatch('delete', ['rowId' => $row->id]),
    ];
}

Files changed:

• resources/js/components/pg-render-actions.js
• resources/views/components/support-livewire-v4.blade.php
• dist/powergrid.js (rebuilt bundle)

Verified with a Livewire 4.4.5 + Tailwind reproduction (120 rows / 10 per page):
action buttons went from 20 → 0 on page 2 before the fix, and 20 → 20 after.
