Add actions field to wp cron event list

[Copilot]

Fix for Failing Test

Issue

The test was failing with Error: Invalid field: actions. because the WP-CLI Formatter validates that requested fields exist on the item objects.

Solution

Initialize the actions property as an empty string on all event objects in format_event(). The lazy-loading logic in list_() then populates it with actual callback data only when the field is explicitly requested.

Implementation Flow

1. All events get an empty actions property during formatting (performance-neutral)
2. When user requests --fields=actions, the property is populated with actual hook callback data
3. The Formatter can now validate the field exists and display it correctly

This maintains the performance benefits of lazy-loading (callbacks are only fetched when needed) while satisfying the Formatter's field validation requirements.

<issue_description>I just updated WP-Crontrol so it also shows the actions attached to each cron event. WP-CLI should do the same when you use wp cron event list.</issue_description>

Comments on the Issue (you are @copilot in this section)

@danielbachhuber FYI - `wp cron event list` now lives in https://github.com/wp-cli/cron-command @danielbachhuber Also, `wp profile` has a `get_name_location_from_callback` that might be useful to abstract to `WP_CLI\Utils`: https://github.com/wp-cli/profile-command/blob/master/inc/class-profiler.php#L469 @danielbachhuber Could/should this be solved with documentation instead?

Use wp hook <hook> to inspect the callbacks on each event.</comment_new>
