fix(dashboard): Crate with UI fixes

[SokratisVidros]

What changed? Why was the change needed?

Pixel perfect implementation of the step editors

The fixes include:

• Teach Codemirror to look and behave exactly like the rest of native HTML inputs regarding focus, rendering with errors, and overflowing with long content (text-wrapping).
• Simplify the CSS logic of the variable pills and ensure they are not causing any jumps to the hosting editor.
• Polish in-app action buttons.
• Use simpler markup to render ControlInputs.
• Apply copywriting fixes
• Add client-side validation to the step creation form to behave exactly like the workflow creation form.
• Fix invalid HTML markup; we were rendering nested buttons on multiple occasions.
• Fix error state rendering for the Avatar Picker
• Perfect Variable popover placement for multiline <ControlInput/>. Now that the editor occupies all the available space, the popover opens relative to the full box of the editor, so it's a bit further down than we want.

Screenshots

It's too late for so many screenshots. I advise reviewers to open the preview deployment next to the latest production deployment and test.
