Neeraj Hotfix Restore Job Analytics Graph Data Rendering

[Neeraj-Kondaveeti]

Description

This PR fixes a regression on the Job Analytics Competitive Roles page where the graph displayed “No data available” after the previous merge, despite valid backend data being present. The issue was caused by frontend handling of backend response variations, which led to valid data being normalized to zero and filtered out before rendering. This change restores the expected behavior by defensively normalizing the response data prior to chart rendering without altering existing filters, aggregation logic, or visual presentation.

Main changes explained:

• Updated the Job Analytics graph component to normalize incoming analytics data before rendering.
• Ensured application counts are derived safely from backend responses that may vary in shape across environments.
• Prevented valid datasets from being incorrectly treated as empty and triggering the “No data available” state.
• Preserved existing chart logic, filtering behavior, and visual presentation.

2. do npm install and ... to run this PR locally

6. Verify the graph renders correctly with default filters (Dates = All, Role = All, Granularity = Totals).
7. Change role, date range, and granularity filters and confirm the chart updates as expected.

• No backend endpoints, query logic, or aggregation behavior were modified.
• The change is defensive and ensures compatibility with existing backend data across environments.
• This PR is safe for immediate merge to restore expected functionality.

Hi Neeraj,

I have reviewed your PR locally and it does work as expected. I would like to point out that in dark mode the calendar is in light mode which reviewers might point out during merge.
