Fix: use UTF-8 safe substr for multibyte support in mod_articles_category
Fixes #45452
Summary of Changes
Replaced the regular substr() function with mb_substr() in mod_articles_category to ensure correct multibyte string handling for UTF-8 encoded text.
Testing Instructions
- Create or open a Joomla site with multibyte characters (e.g., accented or non-Latin characters) in article titles or categories.
- Display those articles using the "Articles - Category" module.
- Verify that the trimming and display of multibyte titles is now correct.
Actual result BEFORE applying this Pull Request
Multibyte characters were sometimes cut off or displayed incorrectly.
Expected result AFTER applying this Pull Request
Multibyte characters are displayed correctly and not truncated.

The code looks OK but I could not figure out how to trigger before/after observations. I tried altering the date filtering options in the module. So testing needs someone with more insight or more specific testing instructions.

I couldn't figure out how to compare before and after. Looking at the description, it's about multibyte support, but the changes in the code only affect lines that deal with a date field. Okay, the addition in these lines certainly makes sense, but I can't understand where multibyte characters should be cut off incorrectly.
Like the previous fellow campaigner, someone with more experience in this area is definitely needed here. A more detailed description of the testing instructions would be helpful.

@Suyash2JZ From reading the issue, which shows a problem with Chinese UTF-8 character cutting in the intro field, I do not understand how UTF-8 safe substr for multibyte support in month/year field could solve the issue?
The code in this PR is completely unrelated to the reported problem
@Suyash2JZ I recommend closing this PR yourself. If we don't hear back from you, we'll close it in one week. You're of course welcome to reopen it or submit a new PR if you want to continue working on it.
