[FE-17] Implement PDF export for single asset report in opsce folder

[yusuftomilola]

Problem

Individual asset PDF reports (BE-24) cannot be downloaded from the UI. The asset detail page has no export functionality despite jsPDF being installed on the frontend.

Proposed Solution

Create frontend/opsce/features/assets/DownloadAssetReportButton.tsx. Call GET /api/assets/:id/report and trigger a file download.

Acceptance Criteria

• Button labeled "Download Report" shown on the asset detail page header
• Clicking calls GET /api/assets/:id/report and downloads the returned PDF
• Downloaded filename: asset-report-{serialNumber}-{date}.pdf
• Loading spinner shown on the button while the request is in progress
• On error, shows a toast: "Failed to generate report. Please try again."
• Button is only visible to ADMIN and MANAGER roles (hidden for VIEWER)
