Feature/model selector

[maartenpaul]

This pull request adds support for custom model selection in workflows, improves the handling and display of available models from the SLURM cluster, and updates the frontend to allow users to select custom-trained models if available. It also ensures that model information is passed through the backend and exposed in the UI.

Backend enhancements for model support:

• The backend now extracts available models for each workflow from SLURM parameters and includes them in the SLURM status response as workflow_models. [1] [2] [3]
• The run_workflow_script function is updated to handle a custom_model parameter, ensuring the selected model is passed to the workflow script if provided. [1] [2]

Frontend/UI improvements:

• The workflow form now displays a "Custom Model" dropdown selector when models are available for the selected workflow, allowing users to pick a custom-trained model from the SLURM cluster. [1] [2]
• The SLURM status indicator updates the application state with available models per workflow, enabling the new UI feature.

Static asset updates:

• Updated asset references in asset-manifest.json and added/modified corresponding JavaScript and license files to reflect the new build, ensuring the frontend changes are deployed. [1] [2] [3] [4] [5]

I would consider this a draft implementation of this NL-BioImaging/biomero#16
These changes collectively allow users to select and run workflows with custom models, improving flexibility and integration with SLURM-managed resources.
