refactor: uplift metrics (#4499)

# Description

This pull request implements a dual-chart system for metrics visualization with brush-based zooming functionality. The changes introduce an overview chart showing 7 days of data with a brush selector, and a detail chart that displays the selected time range with higher resolution data.

Key changes include:
- Added chart synchronization context with default 24-hour brush range and 7-day maximum range
- Implemented separate hooks for overview and detail metrics data fetching
- Enhanced timestamp parsing to normalize date formats for consistent browser compatibility
- Added brush range clamping to prevent excessive data requests
- Removed time range selector in favor of interactive brush-based navigation
- Improved chart layout with proper spacing and legend positioning
- Added placeholder data support to prevent chart flickering during updates

- Verifying brush selection updates the detail chart with appropriate resolution
- Testing brush range clamping with selections exceeding the 7-day maximum
- Confirming timestamp normalization works across different date formats
- Validating smooth transitions between overview and detail data loading states
