[Integration]: Power BI - Report Generation and Dataset Management

[hh3538962]

Reason:
Business Analytics teams need to automatically generate reports, refresh datasets, and export visualizations from Power BI. Currently, after agents complete data analysis, users must manually create and update Power BI reports.

Use case:

• Analytics agent completes monthly sales analysis → automatically updates Power BI dataset and triggers report refresh
• Marketing agent identifies trending products → creates Power BI dashboard to visualize trends
• Finance agent processes quarterly data → generates Power BI report and emails to stakeholders
• HR agent analyzes employee data → refreshes Power BI HR dashboard

Scope (MVP):

• Authenticate with Power BI REST API (OAuth2)
• Refresh datasets programmatically
• Export reports as PDF/PowerPoint
• Create/update dashboards
• Get workspace and dataset information
• Trigger scheduled refreshes

Why this matters:
Business Analytics professionals use Power BI as their primary reporting tool. This integration completes the "analyze → report → distribute" workflow without manual intervention.

I have Business Analytics background with Power BI experience and would like to work on this.

Thanks for the assignment! I'm starting work on this today.

My plan:

• Day 1-2 (Today-Tomorrow): Research Power BI REST API and design the integration architecture
• Day 3: Implement authentication (OAuth2) and basic connection
• Day 4: Implement core features (dataset refresh, report export)
• Day 5: Add tests and documentation

I'll post a Draft PR by Day 3 to show progress. Will keep you updated!
