Feat/dataset experiment chaining

[Irozuku]

This pull request refactors the experiment creation flow to support pre-selecting a dataset and improves code maintainability by modularizing step rendering. It also enhances the user experience by allowing users to launch a new experiment directly from the dataset visualization page, with the selected dataset automatically passed to the experiment creation modal.

User Experience Enhancements

• A "New Experiment" button is added to the dataset visualization page, which navigates to the experiments page and opens the experiment creation modal with the selected dataset pre-filled. [1] [2] [3]
• The experiment creation modal initializes the experiment's dataset field with the preselected dataset if provided, ensuring a smoother user workflow.

Code Quality and Consistency

• Step definitions and rendering are now dynamic, reducing duplication and making future changes easier. [1] [2] [3]
• Redundant imports and logic are removed from NewExperimentModal.jsx, streamlining the component.

Pull Request Overview

This pull request enhances the user experience by enabling dataset-to-experiment chaining, allowing users to launch new experiments directly from dataset visualizations with pre-selected datasets. It also improves code maintainability through better modularization of experiment creation steps.

• Adds a "New Experiment" button to dataset visualization pages that navigates to experiments with pre-selected dataset
• Refactors experiment step rendering into a reusable utility function with dynamic step configuration
• Implements conditional step flow that skips dataset selection when a dataset is pre-selected
