feat(admin): add system logs tab and restrict platform tracking to logged-in users

[Karu174]

📄 Description

As a Staff Admin,
I want to view the background synchronization logs directly from my dashboard,
so that I can monitor the health of the API updates without needing to access the default Django admin panel.

As a platform user (Guest),
I want to be redirected to the login page if I try to access a platform link,
so that I don't receive misleading "Added to history" notifications when I don't have an active session.

✅ Changes Made

• Staff Admin Dashboard: Added a new "System Logs" tab displaying a paginated table of all SyncLog entries (Start Time, End Time, Status, and Summary).
• Middleware Configuration: Exempted the system_logs route in AdminRedirectMiddleware to ensure Staff Admins can access it securely.
• Global Pagination: Created a reusable paginator.html component that correctly handles URL parameters (like platform and date filters).
• Guest UX (Frontend): Modified the JavaScript tracking script in details_base.html. Unauthenticated users are now redirected to the login view when clicking a platform button, preventing ghost API requests and false "success" toasts.

🛠️ Relevant Files Modified

• users/middleware.py & users/urls.py (Routing and permissions)
• web_app/views.py (Added system_logs view)
• users/templates/users/parts/system_logs.html (New UI table)
• Templates/paginator.html (New global component)
• Templates/Details/details_base.html (JS authentication check)
• Staff Admin Tab template (Added the new navigation link)

Closes: #191

📸 Testing Performed

• Admin Test: Logged in as Staff Admin, navigated to the new tab, and verified the logs display correctly with pagination.
• Guest Test: Opened an incognito window, navigated to a detail page, and clicked a platform button -> successfully redirected to the login page.
• Consumer Test: Logged in as a standard user, clicked a platform button -> tracking toast appears correctly without redirecting.
