Fix: SimpleBlogPage paginator TypeError

[sentry]

This PR addresses a TypeError: this.paginator.init is not a function occurring in the ext.simpleBlogPage.ui.panel.BlogList component when viewing user blog pages (e.g., /wiki/User_blog:BlossomVicky218).

Root Cause:
The error stems from a version mismatch between the SimpleBlogPage extension and the OOJSPlus library. The BlogList panel in SimpleBlogPage expects OOJSPlus.ui.data.pagination.Paginator objects to have an init() method, which it calls after the data store loads. However, the OOJSPlus version deployed on the server does not expose this init() method, leading to the TypeError when SimpleBlogPage attempts to call it.

Solution:
This fix introduces a JavaScript compatibility shim (ext.wikioasismagic.simpleBlogPageFix) that dynamically adds a no-operation init() method to OOJSPlus.ui.data.pagination.Paginator.prototype if it is not already defined. This ensures that the call from SimpleBlogPage's BlogList component succeeds without error, while allowing newer OOJSPlus versions (which might natively include init()) to function as intended.

Changes Made:

1. modules/ext.wikioasismagic.simpleBlogPageFix.js (new file): Contains the JavaScript shim to patch the Paginator.prototype.
2. extension.json:
   • Registered the new ext.wikioasismagic.simpleBlogPageFix ResourceModule, with a dependency on ext.OOJSPlus.data.
   • Added the BeforePageDisplay hook to load this module.
3. includes/HookHandlers/Main.php:
   • Implemented the onBeforePageDisplay hook to conditionally add the ext.wikioasismagic.simpleBlogPageFix module to the output, but only when the SimpleBlogPage extension is active. This ensures the shim is only loaded when necessary.

Bug: The onBeforePageDisplay method is defined inside the $specialsArray array literal, which is invalid PHP syntax and will cause a fatal parse error.
_{Severity: CRITICAL}

Suggested Fix

Move the onBeforePageDisplay method definition outside of the $specialsArray array literal. The method should be defined as a class method within the Main class, but after the closing bracket ] of the array.

Potential issue: The `onBeforePageDisplay` method and its docblock have been inserted
directly inside the `$specialsArray` array literal in `includes/HookHandlers/Main.php`.
Defining a method within an array literal is not permitted by PHP's language
specification. This will cause a fatal `Parse error` as soon as the file is loaded by
PHP's autoloader. Because the extension is loaded on every page request, this syntax
error will prevent the `WikiOasisMagic` extension from loading entirely, leading to
application failure on any page that relies on it.
