feat: Upgrade Regional Performance Analytics Dashboard with Multi-Parameter Filtering

[VaibhavChauhan615]

Overview

This Pull Request upgrades the Geographical and Performance Analytics section inside the teacher and admin panel dashboards. Previously, the Analytics page rendered a static list of schools with dummy progress stats and overlapping layout alignment issues.

This PR transforms the Analytics panel into an interactive, multi-parameter dashboard that enables administrators to slice data dynamically, visualize student level growth over time, check gender disparities, and trace learner engagement streaks.

Key Changes

• Multi-Parameter Filtering:
  • Added Time Horizon selection (7d, 30d, 6m, 1y) to scale performance timelines.
  • Added Grade Band filter (Preschool, Class 1, Class 2, Class 3-4) to slice cohort metrics.
  • Added Gender filter (Male, Female) to isolate demographic analytics.
• Expanded Metrics Banner (6 Cards):
  • Calculates Total Schools, Total Students, Avg FLN Level, and Certification Rate (Level 5+ benchmark) dynamically.
  • Added Active Educators (teachers count inside the filtered scope) and Remedial Support Rate (percentage of students requiring intervention).
• Advanced Data Visualization:
  • Integrated a custom, glowing SVG progress line chart showing average student FLN levels over time.
  • Built a strand proficiency breakdown showing mastery levels across different math topics (Number Sense, Operations, Shapes, Measurement, Fractions).
• Demographic & Leaderboard Insights:
  • Added Boy-vs-Girl gender disparities split card comparing avg levels and certification rates.
  • Appended a Regional Performance Ranking leaderboard displaying top-performing jurisdictions vs regions needing support.
  • Integrated active learning streaks tracker (tracking 3+ and 5+ day learner streaks).
• Layout Alignment Fix:
  • Restructured table grid columns with a fixed-width code column (w-36) to resolve the overlapping text overlay bug.

Verification & Performance

• Verified that all workspace projects typecheck and compile cleanly with npm run lint (exit code 0).
• Calculations use optimized Set lookup maps to process metrics in O(N+M) time, ensuring the dashboard rendering is completely lag-free.
