fix(ErrorNodeCard): show error message body in compact (single-node) mode (#9437)

## Summary
Remove the `!compact` condition that was preventing the error message
body from being displayed in compact (single-node error) mode.

## Changes
- **What**: Removed `&& !compact` guard from `v-if="error.message &&
!compact"` in `ErrorNodeCard.vue` so the error message body is always
shown when present, regardless of display mode
