Oliver Kieselbach 6d313d2832 Remove the Teams Office 365 Connector notification provider (D-323) ...

Microsoft switched off the Office 365 connectors in Teams in May 2026. Provider 1,
its MessageCard renderer, the channel editor option and the flat TeamsWebhookUrl /
TeamsNotifyOn* fields with their fallback branch are gone; the value stays retired.

NotificationChannel.IsSupportedProviderType is now the one rule for channel parsing,
channel validation and the flat WebhookProviderType, so a retired or unknown provider
can no longer be stored and come back as a synthesized channel. The channel editor
looks up the placeholder by value instead of by list index. The header-parsing tests
move to NotificationChannel.GetCustomHeaders; manifests and wire types regenerated.
