Create Azure adapter: OperationalInsightsWorkspace (#4540)

<!-- CURSOR_AGENT_PR_BODY_BEGIN -->
## Summary

Creates a new Azure adapter for `OperationalInsightsWorkspace` (Log
Analytics Workspace) resources.

## Changes

### New Files
- `sources/azure/clients/operational-insights-workspace-client.go` -
Client interface wrapping Azure SDK
-
`sources/azure/shared/mocks/mock_operational_insights_workspace_client.go`
- Generated mock client
- `sources/azure/manual/operational-insights-workspace.go` - Adapter
implementation using `ListableWrapper`
- `sources/azure/manual/operational-insights-workspace_test.go` - Unit
tests
-
`sources/azure/integration-tests/operational-insights-workspace_test.go`
- Integration tests

### Modified Files
- `sources/azure/shared/models.go` - Added `Insights` API, `Cluster` and
`PrivateLinkScopeScopedResource` resource constants
- `sources/azure/shared/item-types.go` - Added
`OperationalInsightsWorkspace`, `OperationalInsightsCluster`, and
`InsightsPrivateLinkScopeScopedResource` item types
- `sources/azure/manual/adapters.go` - Registered the new adapter
- `go.mod` / `go.sum` - Added `armoperationalinsights` SDK dependency

## Adapter Details

- **Type**: `ListableWrapper` (top-level resource scoped to resource
groups)
- **Category**: `ADAPTER_CATEGORY_OBSERVABILITY`
- **Health Mapping**: Maps `ProvisioningState` to SDP health status
- **Linked Items**:
- `OperationalInsightsCluster` - via
`Properties.Features.ClusterResourceID`
- `InsightsPrivateLinkScopeScopedResource` - via
`Properties.PrivateLinkScopedResources[].ResourceID` (using composite
lookup key for child resource)
- **IAM Permission**: `Microsoft.OperationalInsights/workspaces/read`
- **Predefined Role**: `Log Analytics Reader`

## Testing

- Unit tests cover Get, List, ListStream, error handling, health state
mapping, and cross-resource-group links
- Integration test creates actual Azure resources and verifies adapter
behavior (skips gracefully if service principal lacks permissions)
- All tests pass locally
