fix(frontend): Disable single dollar sign LaTeX mode in markdown rend… (#11598)

Single dollar signs ($10, $variable) are commonly used in content and
were being incorrectly interpreted as inline LaTeX math delimiters. This
change disables that behavior while keeping double dollar sign ($$...$$)
math blocks working.
## Changes 🏗️
• Configure remarkMath plugin with singleDollarTextMath: false in
MarkdownRenderer.tsx
• Double dollar sign display math ($$...$$) continues to work as
expected
• Single dollar signs are no longer interpreted as inline math
delimiters
## Checklist 📋
For code changes:
	-[x]	I have clearly listed my changes in the PR description
	-[x] I have made a test plan
	-[x] I have tested my changes according to the test plan:
-[x] Verify content with dollar amounts (e.g., “$100”) renders as plain
text
-[x] Verify double dollar sign math blocks ($$x^2$$) still render as
LaTeX
-[x] Verify other markdown features (code blocks, tables, links) still
work correctly
