feat(analytics): Add real-time active users tracking

[zeemscript]

Description

Implement real-time tracking of active users on the platform using Redis for fast, concurrent user counting. This feature provides live insights into platform usage and can help with capacity planning and identifying peak usage times.

Acceptance Criteria

• Track concurrent active users in real-time using Redis
• Update user activity with each request via middleware
• Expire inactive sessions after configurable timeout
• Provide API endpoint to retrieve current active user count

Files to Create

• src/routes/analytics/active-users.ts - Real-time active users endpoint
• src/services/analytics/active-users-service.ts - Redis-based active user tracking
• src/middleware/analytics/activity-tracker.ts - Middleware to update user activity

Hi, I'd like to work on this issue. I'll add Redis-based real-time active user tracking with an activity-tracker middleware updating presence on each request, a configurable timeout to expire inactive sessions, and an active-users endpoint to retrieve the current count, across the new service, middleware, and route files.
