fix(dashboard): resolve wu_moment ReferenceError on network dashboard activity stream

[superdav42]

Summary

• Move wu-activity-stream script enqueue from the view template (activity-stream.php) to Dashboard_Widgets::enqueue_scripts() so it runs during admin_enqueue_scripts where WordPress properly resolves the dependency chain
• Add moment as a declared dependency of wu-functions since functions.js uses moment.tz/moment.utc in wu_moment()
• Add unit test verifying wu-activity-stream is enqueued with correct dependencies on index.php

Problem

The Activity Stream widget on the network admin dashboard was permanently stuck on "Loading..." with:

Uncaught ReferenceError: wu_moment is not defined
    at HTMLDocument.<anonymous> (activity-stream.js:4:10)

activity-stream.js was enqueued inside the view template during widget rendering (meta_box output phase), which fires after admin_enqueue_scripts. WordPress cannot properly resolve the dependency chain for scripts enqueued that late, so wu-functions (which defines window.wu_moment) was not guaranteed to load before activity-stream.js executed.

Fix

Moved the wp_enqueue_script('wu-activity-stream', ...) call from views/dashboard-widgets/activity-stream.php into Dashboard_Widgets::enqueue_scripts(), which hooks on admin_enqueue_scripts. This ensures WordPress resolves the full dependency chain (moment -> wu-functions -> wu-activity-stream) before any script executes.

Also added moment as an explicit dependency of wu-functions since functions.js line 626-634 defines wu_moment() which calls moment.tz() / moment.utc().

Verification

• Browser-tested on the network dashboard: Activity Stream widget now loads and displays events correctly
• wu_moment is not defined error is gone
• All 12 Dashboard_Widgets_Test tests pass (including new test)
• PHPStan clean

📝 Walkthrough

Walkthrough

This change centralizes the enqueuing of the wu-activity-stream script from the dashboard widgets view template to the dashboard widgets class, ensuring proper dependency resolution, explicit nonce injection, and standardized script loading through WordPress's admin_enqueue_scripts hook.

Changes

Cohort / File(s)	Summary
Script Enqueuing Centralization inc/class-dashboard-widgets.php	Added centralized enqueuing of wu-activity-stream script within enqueue_scripts() with explicit dependencies on wu-vue, wu-functions, and moment, plus inline script injection to define wu_activity_stream_nonce before script execution.
Dependency Management inc/class-scripts.php	Updated wu-functions script dependencies to include moment, ensuring proper script load ordering.
View Template views/dashboard-widgets/activity-stream.php	Removed in-template script registration and enqueuing; replaced with comment indicating script is handled by centralized Dashboard_Widgets::enqueue_scripts().
Testing tests/WP_Ultimo/Dashboard_Widgets_Test.php	Added new test test_enqueue_scripts_enqueues_activity_stream_on_index() verifying activity-stream script enqueues with correct dependencies (wu-functions, moment).

Poem

🐰 Scripts once scattered, now unite with care,
Dependencies dance in the enqueue layer,
From view to class, a hop toward the light,
WordPress hooks make everything right,
The nonce arrives before the deed is done—
Organized scripts make coding fun! 🚀
