fix: Correct 'comparsion' spelling typo in locale dictionaries and UI components #228

The word 'comparison' is misspelled as 'comparsion' across 11 translation keys in src/locales/en.json and src/locales/ar.json and referenced in multiple components.

Motivation

Fixing spelling errors in public-facing keys and dictionaries improves code hygiene and translation consistency throughout the project.

Tasks

• Update comparsion.* keys to comparison.* in src/locales/en.json and src/locales/ar.json:
  • comparison.activity.score
  • comparison.contribution.diff
  • comparison.contribution.score
  • comparison.diff
  • comparison.final.score
  • comparison.language.final.score
  • comparison.pr.diff
  • comparison.pr.score
  • comparison.repo.diff
  • comparison.repo.score
  • comparison.score
• Update all calling components referencing comparsion.*:
  • src/features/leaderboard/components/leaderboard-table.tsx
  • src/features/comparison/components/comparison-chart.tsx
  • src/features/comparison/components/comparison-table.tsx
  • src/features/comparison/components/result-dashboard.tsx
  • src/features/developer/components/user-profile-client.tsx
  • src/components/cards/community-card-item.tsx
  • src/components/cards/pr-card-item.tsx
  • src/components/cards/repo-card-item.tsx
• Run pnpm validate-locales to ensure key parity.
• Run pnpm test to verify no broken tests.
