fix(admin): Add null checks for system info rendering

[codeunia-dev]

• Add optional chaining and nullish coalescing for systemInfo properties
• Prevent potential runtime errors when systemInfo is undefined
• Provide default values for system metrics and information
• Improve robustness of system information display in admin dashboard

Summary by CodeRabbit

• Bug Fixes
  • Improved resilience of the system information dashboard by implementing robust handling for missing or undefined data. The page now gracefully displays default values for CPU usage, memory, disk, network, and service metrics instead of breaking when data is unavailable.

Walkthrough

The pull request adds comprehensive null-safety improvements to the system dashboard page by replacing direct property accesses with optional chaining operators and default fallback values throughout the component. This prevents runtime errors when system information fields are undefined.

Changes

Cohort / File(s)	Summary
Null-safety defensive improvements app/admin/system/page.tsx	Added optional chaining (?.) and default fallback values (?? 0, ?? 'N/A') for all system information properties including uptime, CPU usage, memory metrics, disk capacity, network interfaces, service details, and platform information across multiple UI sections.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Single file scope: Changes consolidated to one component
• Highly repetitive pattern: The same optional chaining and default value pattern applied consistently throughout (low cognitive overhead per instance)
• Focus areas: Verify that default fallback values are semantically correct for each field (e.g., 0 for numeric values, 'N/A' for strings) and ensure optional chaining is applied at appropriate nesting levels to avoid masking legitimate errors

Poem

🐰 With gentle chaining, soft and deep,
We guard the fields where nulls may creep,
Each ?? a safety net so near,
No runtime crashes need we fear!
Safe data flows through every screen, ✨
