Code Review
This pull request enhances the telemetry timeline chart by adding a rich tooltip, which is a great improvement for user experience. The implementation is functionally correct. My review includes suggestions to improve type safety by replacing the any type with a specific interface for the tooltip props, and to enhance maintainability by extracting inline styles into CSS classes. These changes will make the code more robust and easier to maintain.

Using any for component props defeats the purpose of using TypeScript, as it bypasses type-checking. Please provide specific types for the props to improve type safety, code clarity, and maintainability. For better readability, you could extract this inline type into a separate interface or type alias above the component.

The component uses a significant amount of inline styling. This can lead to maintainability issues, inconsistencies, and makes the JSX harder to read. It's a best practice to extract styles into a separate stylesheet (e.g., using CSS Modules) or a CSS-in-JS solution, depending on the project's conventions. This will promote reusability and make the component's structure cleaner.

Pull request overview
This PR enhances the Telemetry Timeline chart by adding a rich custom tooltip that displays comprehensive event information. Previously, the tooltip only showed the date and probability; now it includes the event name and subjective notes, providing users with full context directly on the chart without needing to reference the table below.
Changes:
- Extended
getProbabilityData()to includeeventandsubjectivefields in the returned data structure - Replaced the default Recharts tooltip with a custom
CustomTooltipcomponent that displays date, event name, probability, and subjective notes in a styled card format

The CustomTooltip function uses any type for its props, which bypasses TypeScript's type checking. Recharts provides a TooltipProps type from 'recharts' that can be imported and used. Consider defining a proper interface for the tooltip props that extends or uses the types provided by Recharts to ensure type safety.

💡 What: Added a rich tooltip to the Telemetry Timeline chart that displays event names and subjective notes alongside probability.
🎯 Why: Users need context (event type, subjective description) to understand probability spikes without cross-referencing the table.
📸 Before/After: Before: Tooltip showed only date and probability. After: Tooltip shows date, event name, probability, and subjective note in a styled card.
♿ Accessibility: Used semantic HTML and consistent design patterns (
.cardclass) for better integration.PR created automatically by Jules for task 6875996544613906806 started by @igor-holt
