Performance alert system

[MahmoudShawky1612]

Description of the change

This Performance Health Check system works like a pre-flight checklist. Before users perform critical actions, the app automatically checks:

• Memory usage levels — warning if we're approaching dangerous thresholds
• Network connectivity status — so users know why something isn't loading
• Battery levels — preventing actions that might crash low-battery devices## Type of change
• [ ] Bug fix (non-breaking change that fixes an issue)
• [x] New feature (non-breaking change that adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
