Fix/cmm 954 reader when editing a comment markup tags are shown

[adalpari]

Description

When editing a comment in the Reader, the comment text was displaying raw HTML markup tags (e.g., <p>, <br>) instead of plain text. This made the editing experience confusing as users would see the underlying HTML structure rather than the formatted content.

Testing instructions

1. Open the app and navigate to the Reader
2. Find or create a post to comment.
3. Comment it
4. Tap on the comment to view details
5. Tap the three dots icon to edit the comment

• Verify: The comment text should display as plain text without any HTML tags like <p>,<br>, etc
  6. Edit the comment text and save
• Verify: The comment is saved correctly and displays properly
