- Disable enableSlices on ResponsiveLine with single data point (causes
null reference in Nivo internal slice computation)
- Add null check for slice.points[0] in timeline tooltip
- Guard ResponsivePie from empty data array in diversity metrics
- Add fallback for scoreDistribution.distribution on both
observer and admin reports pages

All 9 chart components now have early-return null/empty checks before
calling .map() on data props. The diversity-metrics chart guards all
nested array fields (byCountry, byCategory, byOceanIssue, byTag).
Analytics backend guards p.tags in getDiversityMetrics. This prevents
any "Cannot read properties of null (reading 'map')" crashes even if
upstream data shapes are unexpected.
