Summary: Bettermode adds Chinese localization support

Why It Matters: The platform is expanding its reach to Chinese-speaking users. This makes it easier for global companies to manage communities in multiple languages.

What Changed:

• Added Chinese text ("本地化与翻译") to the Localization & Translation section.
• Updated the description for multilingual support in Chinese.
• Changed the "Discussion" label to "Knowledge-base" in the feature preview.
• Updated reaction labels from numbers to text options like "Loved it!", "Meh...", and "Nope!".
