feat: Improve GitHub issues view with validation indicators and Markdown support

- Added an `isValidating` prop to the `IssueRow` component to indicate ongoing validation for issues.
- Introduced a visual indicator for validation in progress, enhancing user feedback during analysis.
- Updated the `ValidationDialog` to render validation reasoning and suggested fixes using Markdown for better formatting and readability.
