- Consolidate 8 individual stat cards into 4 grouped cards:
* Account Data (Current Balance, Historical Consumption)
* Usage Statistics (Request Count, Statistics Count)
* Resource Consumption (Statistics Quota, Statistics Tokens)
* Performance Metrics (Average RPM, Average TPM)
- Add gradient header backgrounds with white text for card titles:
* Blue gradient for Account Data
* Green gradient for Usage Statistics
* Yellow gradient for Resource Consumption
* Pink gradient for Performance Metrics
- Implement mini trend charts using real API data:
* Replace mock data with actual time-series data from API
* Hide x and y axes to show pure trend lines
* Display trends only for metrics with available historical data
* Remove trend charts for Current Balance, Historical Consumption, and Request Count
- Merge model analysis charts into single card:
* Combine "Model Consumption Distribution" and "Model Call Count Ratio"
* Use responsive grid layout (vertical on mobile, horizontal on desktop)
* Update card title to "Model Data Analysis"
- Optimize chart configurations:
* Hide axes, legends, and tooltips for mini trend charts
* Maintain color consistency between metrics and trend lines
* Improve performance by processing all trend data in single API call
