Test render status

Test render process is divided into four statuses:

• Queue: Looking for available nodes to start the test render.
• Analyzing: Your project files are being checked before rendering starts. The system verifies assets, plugins, textures, and render settings to ensure the project can render correctly.
• Rendering: Your first, middle, and last 3 frames are being rendered for verification.
• Ready: The test render is completed and used to verify the final output quality and estimate the total render cost of the scene.
