Build category popularity chart widget (frontend)

[phertyameen]

Description

Build a horizontal bar chart ranking categories by unique users/puzzles solved, sourced from GET /analytics/categories/popularity.

Why this matters

Category popularity directly informs which puzzle categories need more content investment.

Files to touch

• frontend/src/components/analytics/CategoryPopularityChart.tsx

Acceptance Criteria

• Bars are sorted descending by the selected metric
• Widget supports toggling between unique users and puzzles solved

Notes

This issue is part of the new analytics module effort (tracking, aggregation,
and reporting on player/game activity). Please keep new code inside
backend/src/analytics/ following the same module/controller/service/provider
layout used by existing modules (e.g. progress, streak, quests).
