Channel Announcement Display Issue with Empty Spaces

Description:

When setting the channel description and announcement/description/topic in Rocket Chat, an issue arises where if we only put empty spaces, then also it displays an empty announcement. This behavior is unexpected, as it should not consider leading or trailing empty spaces in determining the content of the announcement/description/topic.

Steps to reproduce:

1. Click on any channel > Room information > edit room
2. Add some empty space in announcement and save

Expected behavior:

It should disregard leading and trailing empty spaces when displaying channel announcements/description/topic. The announcement/description/topic should not be visible if there are only empty spaces within the content.

Actual behavior:

If we put only empty spaces in any one annoucement/description/topic, then also it displays an empty field

Reproduce the issue through a channel's Room information and edit room flow by saving spaces in the announcement, description, or topic fields. Trace the channel display path from that flow and verify the behavior for whitespace-only content and content with surrounding spaces. Done means whitespace-only fields are not displayed as announcements, descriptions, or topics.
