Fix duplicate script modal validation error persisting after close

[sanjacornelius]

Issue & Reproduction Steps

This PR fixes an issue in the Copy Script modal where the "name already exists" validation error would remain visible after closing and reopening the modal.

The error state was not being cleared when the modal was reopened, causing old validation messages to persist even before attempting another duplicate action.

Solution

• Added this.errors = {} to showModal() to reset the modal state before displaying it.
