Support Resizing of the C# Code Editor in the Workflow Designer

[diequeeq]

Feature Request

The C# code editor displayed within the workflow designer for activities like Set Variable is currently fixed at a small size and cannot be manually
resized. This significantly hinders the ability to comfortably write, view, and manage code snippets larger than a few lines.

Details

Expected Behavior

The C# code editor within the activity settings should be manually resizable (e.g., draggable on corners or edges) to accommodate larger code blocks, improving the developer experience.

Actual Behavior

The C# code editor is a small, non-resizable box. This makes development difficult when dealing with more complex C# expressions.

Pre-requisites (Environment)

The issue occurs when C# support is enabled on the server:
UseCSharp() // add to the Elsa Server configuration.

Steps to Reproduce

1. Create a new workflow.
2. From the Primitives category, add a Set Variable activity to the canvas.
3. Select the activity to open its properties panel.
4. In the properties panel, select C# from the dropdown next to the Value field.
5. Attempt to write or view a multi-line C# expression.

Note

While the Set Variable activity is used as a simple example to reproduce the issue, this applies to all activities in the workflow designer that utilize the same embedded C# code editor.
