Add --preview flag for 'rad app graph' and 'rad app status'

[lakshmimsft]

This pr adds --preview flag support to rad app graph and rad app status commands. When --preview is passed, these commands operate againstRadius.Core/applications resources via the v20250801preview API surface, instead of the default Applications.Core/applications.
This completes the rad app preview command set, following the prior PR that added rad app show/list/delete --preview.

Notes:

• rad app graph --preview — Calls the v20250801preview GetGraph custom action directly. Renders the application graph in table (text) or JSON format. Returns a friendly 404 error if the application does not exist. Includes a v20250801preview-specific display() function for graph rendering.
• rad app status --preview — Fetches the Radius.Core/applications resource via the new client, enumerates owned child resources usingownership-based filtering (properties.application), and gathers public endpoints via the diagnostics client. Outputs status table andgateway table.
• Exported helpers — StatusFormat(), GatewayFormat(), ProviderFromID(), and MakeResourceHyperlink() are now exported from existingpackages so preview subpackages can reuse them without duplication.
• Test client factory — NewRadiusCoreTestClientFactory gains a variadic applicationsServer parameter (backwards compatible).WithApplicationsServerNoError() now includes GetGraph support.
• wirePreviewSubcommand tests — Added unit tests verifying the --preview routing dispatches correctly.

Type of change

• This pull request adds or changes features of Radius and has an approved issue ( rad app commands don't work for applications created by Radius.Core/applications type #11675).

Fixes: #11675

Pull request overview

Adds --preview support for rad app graph and rad app status so these commands can operate against Radius.Core/applications@2025-08-01-preview (v20250801preview) resources, completing the rad app preview command set.

Changes:

• Add preview implementations for rad app graph and rad app status and wire them via --preview routing in the CLI root.
• Export shared formatting and hyperlink/provider helpers so preview subpackages can reuse existing logic.
• Extend the Radius.Core CLI test client factory and add unit tests for preview command behavior and --preview routing.
