fix(legacy-preset-chart-nvd3): sanitize tooltip HTML built from chart data

Several tooltip generators in this module build HTML strings from chart
data and return them to be rendered via D3 `.html()`, but did not run the
result through DOMPurify the way the sibling generators in the same file
already do. Apply `dompurify.sanitize()` to the returned HTML in
`generateBubbleTooltipContent`, `generateMultiLineTooltipContent`, and the
`tipFactory` annotation tooltip callback so data-derived values are
rendered as text rather than markup.

Adds regression tests asserting that script/handler markup in the
data-derived fields is stripped from the generated tooltip HTML.
