Easy Updates Manager Premium

* TWEAK: Improve MPSUM_Logs::normalise_call_stack_args() method to reduce the size of call stacks being stored in the database, also to prevent silent termination due to size of the call stacks that swell * TWEAK: Get rid of PHP 8.1+'s "automatic conversion of false to array is deprecated" message when first time activating the plugin * TWEAK: Add a user capabilities check when receiving a request through the `wp_ajax_eum_ajax` handler * TWEAK: Prevent PHP8+ ErrorException and/or suppress PHP notice/warning for undefined stdClass::$plugin and/or stdClass::$theme variables during auto-updates (this usually happens due to the plugin or theme doesn't follow WordPress standards) * TWEAK: Remove notices regarding WP_AUTO_UPDATE_CORE and AUTOMATIC_UPDATER_DISABLED constants from force automatic updates screen as they now won't prevent automatic updates from being run * TWEAK: Get rid of PHP deprecated message on PHP 8.1+ when presenting admin constant notices by removing sprintf() function that shouldn't had wrapped the esc_html_e() function * TWEAK: All updates settings should be compatible and compliant with WordPress Site Health * TWEAK: Prevent making a nonce available to logged-in users who could not manage Easy Updates Manager (no impact as all actions (dismissal of notices) were unreachable without proper user capability) * FIX: Wrong parameters order in PHP implode() function calls for showing a list of plugins and/or themes that are under version control * FIX: Some fields were not cleared when switching from one auto-update schedule time to another
