Modifies relationship field to react to changing relationTo

Editor assessment

The subject describes the new behavior clearly: the relationship field reacts when relationTo changes, keeping the admin UI consistent with dynamically reconfigured fields. The feat type matches a capability adjustment, and scope absence is offset by naming the field and the prop that drives it. No body is present; explaining whether the options reload or remount, and why the change was needed, would add depth, but the message is intelligible alone and the change is contained. Style is clean — verb-led subject, no trailing period, no junk, no footers. Good and publishable.
