feat: allow multiple inputs in workflow and schedule screens

[aschiavon91]

Description & motivation 💭

The UI was not handling multiple workflow inputs properly, causing silent failures in the "Start Workflow Like This One" experience.

Due to the lack of proper handling for all workflow inputs, users could inadvertently start a workflow with missing inputs, breaking execution expectations downstream.

• Start a new workflow with more than one input, check if inputs are been sent.

• Click on the 'Start Workflow Like This One' button, check if all inputs are visible.
