Fix ESLint configuration, removes the duplicate .eslintrc, and fixes formatting, quotes, and import ordering
Existing React hook dependency violations are locally suppressed with TODOs to avoid behavioral changes. ESLint and related tests pass

Yikes! 244 files changed! Tests failing, do we have a mismatch in our version of eslint or something with what you are running locally and what is configured for CI?

@bnmnetp
Thanks for notice. I’ve fixed the linting issue, CI configurations in normal. The remaining test failure is unrelated to ESLint.
It comes from test_do_assignment_own_course_not_redirected, added in commit ebe4c19.
The test reaches code that depends on BOOK_PATH, which is available locally but is not configured in CI as I understand.
I noticed the same test failure in other PRs (e.g. #1520)
Could you take a look at this?

OK, I pushed the fix, you may need to rebase. to get it.
