Format mismatch between VulnerabilityView and TrackChanges (code block newlines)

[ZuhaibT]

Description

The VulnerabilityView and TrackChanges (peer review) WYSIWYG editors serialise code block newlines using different HTML representations. This causes content saved by one editor to render incorrectly in the other — specifically, newlines inside code blocks are lost or broken when content is round-tripped through peer review.

Steps to reproduce

1. Navigate to /portal/VulnerabilityView and add a vulnerability with a multi-line code block in the Details field.
2. Submit the assessment for peer review.
3. Open peer review and and observe the Details field.
4. Add newlines that are missing to reflect Vulnerability View and Add new content on a newline as a mock suggestion.
5. Complete the peer review and accept the changes as the assessor.
6. Navigate back to /portal/VulnerabilityView and observe the Details field.

Expected behaviour

• TrackChanges editor should render exactly as they appeared in the VulnerabilityView — newlines inside code blocks preserved
• Accepted peer review changes should render in VulnerabilityView exactly as they appeared in the TrackChanges editor — newlines inside code blocks preserved.

Actual behaviour

• Code block newlines are lost in Peer Review / Vulnerability View
• Inline code items collapse or split unexpectedly.

These details are saved in faction db's Vulnerability Collection
VulnerabilityView saves to DB as:

<div class="toastui-editor-ww-code-block"><pre><code>1\n2\n3</code></pre></div>
<p><code>a b c</code></p>

Rendered as shown in Screenshot # 1

After accepting TrackChanges edits, DB contains:

<pre><code>1<br />2<br />3<br />4</code></pre>
<p><code>a</code></p>
<p><code>b</code></p>
<p><code>c</code></p>
<p><code>d</code></p>

Rendered as shown in Screenshot # 4

Key difference:

• VulnerabilityView uses literal \n for newlines; TrackChanges uses <br />
