Going to approve these changes for editMeetingTimes.js

The other file changes have beeen approved as well though they're from other PRs (fine for now).

We will need to revisit this component in the future to use a modal provided by MUI, but that is outside the scope of this PR. Thank you!

@JackHaeg can I ping you to track that this component needs to be transferred to a modal provided by MUI? I think we already have an issue open for it
