fix: load autosave-handler.js on about_page edit view, persist contact group deletion

Two fixes:

1. about_page edit was missing autosave-handler.js: the first if block
   (editType === 'page' || 'about_page') overrode $extraJs with only
   overtype.min.js, making the elseif that added autosave-handler.js
   unreachable for about_page. Added autosave-handler.js to the first
   block, removed dead 'about_page' from the elseif.

2. Deleting a contact group (Contacts 3/4/5) only removed the DOM
   element but never triggered htmx autosave. Dispatched a 'change'
   event on the form after removal+reindex so the hx-trigger fires.

Also expanded autosave-handler.js URL filter to accept apropos.php
so the status indicator (Enregistrement/Enregistré) works for contacts saves.
