patch/keep image inputs in order on multi-image nodes

[iammojogo-sudo]

If an extension node has multiple image inputs (front/left/back/right
style), skipping a middle one used to shift everything after it up a
slot — e.g. wire front + left + right but skip back, and right would
end up getting treated as back.

This keeps each image tied to its actual handle, so a skipped slot just
stays empty instead of bumping the rest. Only touches workflowRunStore.ts.

Tested locally with a multi-image extension, all the skip combos work right.

No need to add before 0.4 :)

NOTE:
This, Im sure you know isn't vital. It's only required for likely some extensions that handle multiple inputs, which are only a few. Thats why it was updated after the other three.
