Open Energy Dashboard: Enhancing "Sec. In Rate" Customization

We'll be making improvements to the Open Energy Dashboard data visualization project. A suggested first issue is "standard choices for sec. in rate" (#1216). Our team has been assigned to enhance the "sec. in rate" option within the create/edit unit customizations, ensuring an effective user experience.

We had very little experience coding with react or doing any major work with web-development , but working on this OED enhancement issue really helped us gain an interest for web-development. We used React, Typescript, and Redux to make drop-down menus for a "sec in rate" property within the Units section in OED so that admins have a easier time choosing standard or custom values when making a unit.

We had trouble with understanding how to use React hookstate and how to code with TypeScript and React to create a drop-down menu. However, we got help from the OED maintainer and CodeDay's help desk to get us closer to our solution.
