Aligning the array UI implementation

[sangwoohaan]

The implementations of array UI seem to be different in some action nodes.

Branch : Switch - has an unnecessary 'value' label between 'Case' and the array.

Intent recognized, Delete properties - missing the stroke below the title

In prompt nodes - indented, and missing the stroke
