Add complete map analytics pipeline to answer: "Which maps drive the most
players? Is my rotation working?"
Backend Changes:
- Migration 005: Add map_id FK to server_stats and wipe_history tables
- Stats consumer now captures current_map_id when persisting stats
- Map analytics queries: get_map_analytics() returns performance metrics,
effectiveness scores, and rotation health
- API endpoint: GET /api/analytics/maps?range=90d returns summary with
best performing map and rotation effectiveness percentage
Frontend Changes:
- MapAnalyticsView.vue: Complete dashboard with performance charts,
sortable metrics table, actionable insights, and CSV export
- ECharts bar chart comparing avg vs peak players per map
- Color-coded effectiveness scoring (green ≥80%, yellow ≥60%, red <60%)
- Time range selector: 30d/90d/all
Purpose: Enables data-driven map selection for wipe day based on player
engagement metrics. Rotation effectiveness algorithm scores maps by
(avg_players / peak_players) * 100.
