Quick Task 260425-w2i: 区域转移概率统计

Plan

1. Model — Add getZoneTransition($periods) method to app\admin\model\History

   • Query latest $periods periods ordered by openTime ASC
   • Divide numbers 1-49 into 5 zones: 1-10, 11-20, 21-30, 31-40, 41-49
   • For each consecutive pair of periods, record (current_zone → next_zone)
   • Return: {zones: ['1-10','11-20','21-30','31-40','41-49'], matrix: [[count...]], probabilities: [[prob...]], total_transitions: N}

2. Controller — Add zoneTransition() method to app\admin\controller\History

   • Accept periods param (default 100, range 10-500)
   • Add to $noNeedRight list
   • Call model method, return JSON response

3. Dashboard — Include zoneTransition in getDashboardData() response

4. Frontend JS — Add zone transition heatmap/table in public/assets/js/backend/dashboard.js

   • Render as a 5×5 matrix table with color-coded cells showing count and percentage
   • Append below existing heatmap section
