fix(metrics): correct 1d revenue, chart date safety, globe zoom, UA merge, region locale

- metrics-page: derive revenue total from daily revenue series so the 1d view
  no longer shows $0 (hourly composed data has no revenue granularity)
- line-chart: make formatChartXAxisTick resilient to unparseable dates instead
  of throwing (the prior NaN check was unreachable)
- globe: disable OrbitControls zoom in non-interactive mode so the globe no
  longer captures page scroll
- analytics batch route: preserve non-object event.data instead of dropping it;
  only stamp the fallback User-Agent onto object payloads
- top-lists: use a fixed 'en' locale for region names to avoid SSR hydration
  mismatches (dashboard UI is English-only)
