chore(version): pre-release bump to 02.52.19-dev [skip ci]

The pre-update backup ran synchronously in onExtensionBeforeUpdate with
no browser feedback — the page just hung until backup + update finished.

Now the system plugin injects JavaScript on com_installer and
com_joomlaupdate pages that intercepts the update button, shows a
Bootstrap modal with a progress bar, and runs the backup via the
stepped AJAX API (ajax.init + ajax.step). On completion it proceeds
with the original update. On failure it shows Skip & Cancel buttons.

The server-side handler remains as a fallback for CLI/API updates.
A session flag prevents double-running when JS already handled it.
