.SYNOPSIS
Legt die App-Registrierung fuer den Intune Manager an (oder aktualisiert sie)
inkl. Graph-Berechtigungen, Public-Client-Flow und Redirect-URIs.
.DESCRIPTION
Deckt genau die Punkte ab, an denen der erste Login sonst mit
AADSTS500113 / AADSTS50011 scheitert:
* Delegierte Microsoft-Graph-Berechtigungen (nach Bedarf: RW, RO, Geraete)
* "Oeffentliche Clientflows zulassen" (isFallbackPublicClient = true)
* Redirect-URIs fuer Device-Code (nativeclient) und WAM-Broker
* optional Admin-Consent
Nutzt nur Microsoft.Graph.Authentication (Invoke-MgGraphRequest) — dieselbe
Abhaengigkeit wie das Tool selbst. Berechtigungs-IDs werden LIVE aus dem
Graph-Service-Principal aufgeloest, es sind also keine fest verdrahteten
GUIDs noetig (die sonst leicht veralten).
.PARAMETER DisplayName
Anzeigename der App-Registrierung. Default: "Intune Manager".
.PARAMETER ClientId
AppId einer BESTEHENDEN Registrierung, die aktualisiert werden soll.
Ohne diesen Parameter wird eine NEUE App angelegt.
.PARAMETER MultiTenant
App fuer mehrere Tenants (signInAudience = AzureADMultipleOrgs).
Default: nur der aktuelle Tenant (AzureADMyOrg).
.PARAMETER ReadOnly
Verwendet die Read-Only-Berechtigungen (fuer eine reine Anzeige-/RO-App,
passend zu clientIdRo im Tool).
.PARAMETER IncludeDeviceActions
Nimmt zusaetzlich die Berechtigungen fuer den Geraete-Tab auf
(Read + ReadWrite + PrivilegedOperations = Sync/Reboot/Lock/Wipe/Retire).
.PARAMETER GrantAdminConsent
Erteilt direkt tenantweiten Admin-Consent fuer die gesetzten Scopes.
Benoetigt entsprechend privilegierte Anmeldung.
.PARAMETER EmitManifest
Gibt zusaetzlich den requiredResourceAccess-Block als JSON aus (zum manuellen
Einfuegen in das App-Manifest im Portal).
.EXAMPLE
# Neue Single-Tenant-App inkl. Consent:
.\Setup-AppRegistration.ps1 -GrantAdminConsent
.EXAMPLE
# Bestehende App um Geraete-Rechte erweitern:
.\Setup-AppRegistration.ps1 -ClientId "51477347-...." -IncludeDeviceActions -GrantAdminConsent
.NOTES
Vorher einmalig: Install-Module Microsoft.Graph.Authentication -Scope CurrentUser
