[Enhancement] [Starlight BE NestJS]Fix Admin Dashboard Graphs Not Rendering on Page Load

[SasaMama01]

Description:
The graphs in the admin dashboard are not rendering correctly when the page loads, forcing users to refresh the page for the graphs to display. The issue is likely related to the graph rendering logic not being triggered properly on initial load. The task is to investigate and resolve the issue so that graphs load correctly the first time.

Purpose:
Improve the user experience by ensuring that graphs render immediately when the admin dashboard page is loaded, without requiring additional steps like refreshing the page.

Requirements:
Investigate the current graph rendering logic to identify where the issue is occurring.
Ensure that the graph rendering function is correctly triggered during the initial page load.
Verify that any dependencies (like data fetching or timing issues) are addressed so that graphs render consistently.
Test across different devices and browsers to confirm consistent behavior.
Expected Outcome:
When the admin dashboard loads, all graphs render correctly without requiring the user to refresh the page.

Acceptance Criteria:
The graphs on the admin dashboard render immediately upon the first page load.
The issue is resolved across all supported browsers and screen sizes.
No additional refresh or user intervention is needed for graphs to display.
