Extract chart visualization feature from PR #2867

[Copilot]

New Pull Request Checklist

• I am not disclosing a vulnerability.
• I am creating this PR in reference to an issue.

Issue Description

PR #2867 contains 194 files changed due to rebase conflicts, mixing the chart visualization feature with unrelated changes (line endings, workflows, package bumps). This PR extracts only the chart feature.

Approach

New Components

• ChartVisualization - Renders bar/line/pie charts for selected cells with time series support
• DraggableResizablePanel - Reusable draggable/resizable container

Modified Components

• Toolbar - Added chart toggle button next to stats dropdown
• DataBrowser - Chart panel state management, renders visualization when selectedData.length > 1
• BrowserToolbar - Passes chart props through to Toolbar

Data Selection

• Extended handleCellClick to accept Number, Date, String columns (not just Number)
• Separates numeric data for sum operations vs. all data for visualization
• Auto-detects time series via Date columns

Dependencies

• React 16 compatible versions: [email protected], [email protected], [email protected], [email protected]

Result: 10 files changed (vs. 194), webpack builds clean, CodeQL passes.

TODOs before merging

• Add tests
• Add changes to documentation (guides, repository pages, in-code descriptions)

Original prompt

Create a new PR based on #2867 with only the changes needed for the chart visualization feature. The old PR has rebase issues and therefore contains a lot of unrelated changes.
