feat(azure/entra-id): frontend panel — AzureEntraIdPanel (IW-265)

[eyriehq-bot]

Summary

• Adds AzureEntraIdPanel.jsx and manifest.js to azure/entra-id/
• Table: Name | App ID | Type | Enabled — all columns sortable
• Detail drawer: Overview (app_id, service_principal_type, account_enabled) + Tags section
• Status pill: Enabled → green, Disabled → gray
• No Metrics button — Entra ID has no Azure Monitor metrics
• Follows the same fetchPlugin + useData + AlertBanner pattern as AzureVirtualMachinesPanel
• Icon: Users (lucide-react)

Test plan

• Panel loads without errors at /plugins/azure/entra-id
• Empty state renders when no service principals collected
• Table rows are sortable (Name, Type, Enabled)
• Status pill correctly shows Enabled (green) / Disabled (gray)
• Clicking a row opens the detail drawer
• Drawer shows Overview, Tags sections (tags section hidden when empty)
• No Metrics button in drawer header
• Escape key closes drawer
• Refresh button triggers SSE stream

Closes IW-265
