Adds a collapsible histogram chart to the CWV section showing how origins are distributed across performance buckets for LCP, CLS, INP, FCP, and TTFB. Features: - Column chart with bars color-coded green/orange/red by CWV thresholds - Dashed plotlines marking good/needs-improvement boundaries - Tail buckets aggregated into an overflow "X+" bar so all origins are shown - Metric selector in the collapsed summary bar for quick switching - Loading spinner while the API call is in progress - Error message when data is unavailable - Light and dark mode support with theme-aware colors - Anchor link (#section-cwv_distribution) with auto-expand on direct navigation - URL hash updates when the section is expanded Fetches data from /v1/cwv-distribution (HTTPArchive/tech-report-apis#105) with technology, date, rank, and geo parameters. Also scopes the global .highcharts-point CSS rule to line/spline series only, so column chart bar colors are not overridden. Closes HTTPArchive#1147

Summary
Adds a "Show distribution" button to the Core Web Vitals timeseries card that reveals a histogram of how origins are distributed across performance buckets. Also refactors the existing "Show table" and "Show geographic breakdown" into a unified button bar for a more compact, power-user-focused UI.
