feat: Create Substances Component

[faculedesma]

• Substance component contains all the possible drug choices. Data should be taken from a static array as well and displayed as a selectable list.
• The object of each substance should contain: id, name, combinations. The last one should be an array as well with all the effects between two combined substances (information & result_id).
• When two items are selected then CombinationResult component should react to that state change and display the expected result. The implementation of the last is not included here.
