Update custom icon

Updates an existing custom icon by replacing its image.

What can be updated:

• Image only: The icon image can be replaced with a new one
• Name is readonly: The icon name cannot be changed after creation

How to update a custom icon:

1. Upload a new image file (PNG or SVG format) using POST /api/public/workspace/upload
2. Get the file ID from the upload response
3. Use the file ID in the imageId field

Note: This endpoint requires the CustomIcons.create permission. The icon name remains unchanged - only the image is updated. The updated icon will be reflected throughout the workspace wherever it’s used.
