Do Not Disturb (DND) dropdown option for UK and EU tenants to define call routing behavior when on DND.

Currently for UK and EU accounts, when users enable Do Not Disturb (DND), incoming calls are automatically rejected with default behavior (e.g., busy tone or system-defined action).
There is no user-level or admin-level control over how calls are handled while DND is active.

This feature request proposes adding a dropdown menu under DND settings for UK and EU tenants, allowing them to select how incoming calls should be routed during DND.

When DND is enabled, users (or admins) can choose one of the following actions via a dropdown:

Send to Voicemail – Route all incoming calls directly to voicemail.

Forward the Call – Allow users to specify a forwarding number or extension.

Play Announcement – Play a pre-configured message
