refactor: clean up checklist structure + node renderer

[IMB11]

• Applies component standards to the checklist + node renderer components
• Node renderer has moved back into apps/frontend
• Node renderer now works like:

type NodeRendererDescriptor =
	| { type: 'action' | 'checkbox' | 'toggle' | 'dropdown' | 'text' | 'markdown' }
	| { type: 'custom'; key: string }

/// ...

withRenderer(node, {
	renderer: { type: 'action' },
})

/// then frontend maps the type to an actual component:

const builtinRenderers = {
	action: { component: ActionButton, ... },
	checkbox: { component: Checkbox, ... },
	toggle: { component: Toggle },
	dropdown: { component: Combobox, ... },
	text: { component: StyledInput, ... },
	markdown: { component: MarkdownEditor, ... },
}

this is in line with how we do it for the server panel's audit log table, which has lots of data defined ui in the table
