fix: add ignore_user_abort + fallback completion detection for cron

Browse Source 
The WP-Cron loopback is also subject to Hostinger's 120s timeout.
Adding ignore_user_abort(true) keeps the PHP process alive after
LiteSpeed closes the connection.

Also adds fallback completion detection: if the transient is stuck
at "running" but the generation lock was released (pipeline finished),
the status endpoint now checks for recently-created posts to confirm
success and recover gracefully.
