More testing and cleanup of legacy components

[aaronchongth]

What's new

Addresses some points from #984

• Lots more tests, but leaving out a large chunk of testing TaskForm as we will migrate to json-forms soon
• Clean up legacy components, low-resolution custom logic

Self-checks

• I have prototyped this new feature (if necessary) on Figma
• I'm familiar with and follow this Typescript guideline
• I added unit-tests for new components
• I tried testing edge cases
• I tested the behavior of the components that interact with the backend, with an e2e test
