fix: resolve TextView font style persistence in RecyclerView (#120)

[graycreate]

Summary

• Fixed font style persistence issue when scrolling through topic replies and other RecyclerView-based lists
• Clears TextView content and movement method before applying RichText to prevent style carryover during view recycling
• Addresses issue 部分帖子详情页面，上下滑动页面时，帖子内容字体样式会变动 #120 where users reported text formatting changes randomly when scrolling

Problem

When scrolling through posts in the topic detail page, the font styles (bold, italic, links) would randomly appear on text that shouldn't have them. This was caused by RecyclerView's view recycling mechanism where previously styled TextViews weren't properly cleared before reuse.

Solution

Added explicit clearing of TextView content and movement method before applying new RichText content across all adapters that use RichText rendering:

• TopicReplyItemDelegate: Clear reply content TextView before rendering
• SearchModule: Clear search result content before applying RichText
• UserHomeModule: Clear reply content TextView in user profile
• MsgModule: Clear notification content TextView

Testing

• ✅ Built debug APK successfully
• ✅ Lint checks passed
• ✅ No compilation errors

Fixes

Closes #120

• The line contentView = holder.getView(R.id.content_tv); was removed but this assignment appears to be necessary since contentView is used in subsequent lines. Without this assignment, the clearing operations and RichText rendering will operate on the wrong TextView reference.

        TextView contentView = holder.getView(R.id.content_tv);
