@copilot Make it not internal and add mdx, stories and e2e tests

Done! Removed @internal tag and added:

• MDX documentation with usage examples and related components
• Storybook stories with insight facets that auto-open the modal
• E2E tests with page object, fixture, and test cases for modal visibility, title, close button, filters section, and view results button
• Comprehensive JSDoc documenting all shadow parts

I highlighted a potential slight memory leak, but I don't think it's super big since it's just 1 modal at once.

You can decide what to do with it, I'm sure we had this issue before also.
