feature: Highlight Keywords Missing in Mobile App

Feature Description

In the Rocket.Chat web application, under user preferences, users can set up highlight keywords that notify them when specific words are mentioned. This feature is not currently available in the Rocket.Chat mobile app, resulting in a feature gap between platforms.

Motivation and Use Case

Highlight keywords are essential for power users who rely on custom triggers to stay updated in busy channels. Without this feature on mobile, users may miss important messages when away from desktop.

Implementation Ideas

Introduce a “Highlight Keywords” section under Preferences in the mobile app to mirror the functionality of the web version.
