[BE-59] Member attendance history and admin attendance report

[yusuftomilola]

Overview

Members have no way to see their own check-in history or total hours used. Admins cannot view aggregate attendance patterns. Attendance data is captured in WorkspaceLog but is never surfaced through a useful API.

Context

• WorkspaceLog entity (check-in/out records): backend/src/workspace-tracking/ — fields: userId, workspaceId, checkInTime, checkOutTime
• WorkspaceTrackingController: backend/src/workspace-tracking/workspace-tracking.controller.ts
• DashboardModule admin analytics: backend/src/dashboard/providers/admin-analytics.provider.ts

Tasks

• GET /workspace-tracking/history — paginated check-in/out log for the authenticated member:
  • Response: { data: [{ date, workspaceName, checkInTime, checkOutTime, durationMinutes }], total, page, limit }
  • Supports ?from= and ?to= date filter (ISO 8601)
• GET /workspace-tracking/history/summary — member's personal stats:
  • totalHoursThisMonth, totalDaysThisMonth, currentStreak (consecutive calendar days with at least one check-in), longestStreak
• Admin: GET /reports/attendance — aggregate attendance data:
  • dailyCheckIns: array of { date, count } for the last 30 days
  • peakHours: array of { hour (0–23), averageCheckIns } computed from all historical data
  • averageSessionDurationMinutes
  • topWorkspacesByCheckIns: top 5 workspaces by check-in count this month
