Allow changing the host/instance for existing scripts

[Eistee82]

The Problem

I currently run a setup with multiple ioBroker hosts on different systems, and I have multiple JavaScript adapter instances running across these hosts. When I create a new script, I can choose which JavaScript instance (and thus, which host) it will run on. However, if a script is already created and assigned to a specific instance, there is no direct option to change its assigned instance to a different one on another host.

The Proposed Solution

I propose adding a feature to allow users to change the host/instance for an existing script, similar to how the host can be changed for an entire adapter instance in the ioBroker administrative interface.

This would involve:

Adding a selection option (e.g., a dropdown menu) to the script's settings or context menu in the ioBroker Script Engine (Admin UI).

The dropdown should list all available JavaScript instances across all connected hosts.

Selecting a new instance/host would update the script's configuration to run on the newly selected instance.

Why this is helpful

This feature would significantly improve flexibility and management in multi-host setups, making it easier to:

• Migrate scripts between hosts for load balancing or system maintenance.
• Reorganize script execution without needing to manually copy/paste and recreate scripts, which can be time-consuming and error-prone.

Thank you for considering this feature request! 🚀
