Increase default Cypress command timeout

[williamjallen]

One of our Cypress tests has been particularly flaky lately. This appears to be due to the CI runners executing slowly, with API wait times exceeding the default 4-second timeout Cypress provides. This PR increases the default command timeout to 30 seconds.

A recent flaky test result: https://open.cdash.org/tests/1583856484
