Forum decodes HTML entered as Encoded HTML

[Timo-Breumelhof]

Describe the bug

The Forum Decodes HTML entered in the WYSIWYG editor (with the intention to show it as text).
This prevents users from posting code in the forums (is being stripped converted from text, so encoded HTML to HTML, right now)

Software Versions

• DNN: 09.08.01
• Module: 06.05.01

To Reproduce

Steps to reproduce the behavior:

1. Create a post (with HTML allowed in the forum settings)
2. In the CKEditor post <span>test</span> (not in the Source)
3. Save the post, you will see test rendered by the forum
4. Edit the post, you will only see "test" in the CkEditor, but the span has been placed in the HTML source instead of stored as encoded HTML.

Expected behavior

Encoded HTML should not be converted, but left as entered

IMO the Decode on this line should be removed.

Dnn.CommunityForums/class/Utilities.cs

Line 553 in aada41b

var strMessage = HTMLDecode(text);

After that <p>text</p> stays HTML encoded and is saved the way it should be.
But when you Edit the text after that, the HTML is decoded again (in the editor), not sure if that's by module or CkEditor.

I'm not sure I understand what's happening here. Maybe something is missing the Steps to Reproduce? 🤔

@hismightiness ok, edited, better now? BTW I found one part of the fix, working on the other part..
