Technical details
The delete-team-member RPC command failed to validate that the target member is not the team owner before allowing removal by a non-owner administrator. An authenticated team admin can call this RPC to delete the owner's team-profile-rel membership without authorization checks, bypassing the existing protection present in update-team-member-role. The fix validates member existence and rejects deletion if the target is the owner and the caller is not the owner.
