docs: Fix all 19 Mintlify MDX parsing errors causing deployment failures

[promptless]

Resolves all MDX parsing errors that were causing Mintlify deployment to fail. The errors were caused by various syntax issues where MDX's JSX parser was attempting to parse plain text as JSX expressions. Fixed by escaping angle brackets as HTML entities, converting invalid comment syntax to MDX format, wrapping curly brace expressions in backticks, and converting malformed HTML tags to proper markdown.
