Beautify code to match standardized style guide

[yunchae-kim]

Some of the codes are not formatted to the standardized format according to the style guides implemented in issue-#47.

The goal is to beautify all the codes currently in comptox_ai in order to

• apply the newly agreed style guide and have a standardized coding format for the team
• minimize format changes when making feature pull requests so that the modifications better reflect the changes in feature codes, not the format changes
• clean unnecessary codes and allow efficient code revision

The formatting task should be a long term task done from time to time with low priority. It should be done by bundling files into relevant categories and fixing each bundle per commit (e.g. app components, python tests, python functions, react tests).

Communication between team members is essential in order to avoid merge conflicts and the bundles chosen to beautify should be codes that are not currently being worked on.
