refactor(reports): export report generation utilities for JSON, CSV, and PDF formats in [reports.ts]

[mspandey]

Problem

Currently, reports.ts implements client-side carbon footprint report export utilities (downloadJsonReport, downloadCsvReport, and downloadPdfReport) utilizing jsPDF, jspdf-autotable, papaparse, and file-saver. Ensuring clean ES module exports is essential for maintaining reliable reporting workflows across sustainability analytics dashboards.

Proposed Solution

Verify and maintain clean ES module exports for downloadJsonReport, downloadCsvReport, and downloadPdfReport in reports.ts.

Acceptance Criteria

• Export downloadJsonReport, downloadCsvReport, and downloadPdfReport functions from reports.ts.
• Ensure PDF auto-tables, CSV unparsing, and JSON blob file downloads handle summary metrics and organization telemetry correctly.
• Verify that importing report generation utilities into frontend export components passes all test suites successfully.
