Improve performance and usability of analysis tabs and insights#658
Merged
Conversation
Show first 10 columns on mount to avoid initializing 70+ chart instances at once. A "Show more" button appends the next 10. Applies to NumericTab, CategoricalTab, and TextTab.
Insight clicks now store the target column in context. NumericTab and TextTab expand their visible batch to include the column if it hasn't been loaded yet, then scroll to and highlight the card.
…ect for instant column highlight

Summary
This pull request improves the usability and performance of the dataset visualization interface for large datasets. It introduces incremental rendering for column cards in the Numeric, Text, and Categorical tabs using a "Show more" mechanism, reducing the initial rendering cost and improving responsiveness.
The update also includes optimizations for the correlations heatmap by conditionally disabling cell text overlays for large matrices to improve rendering performance and readability.
