1.0.4: UI quality-of-life improvements

- Added a 'resubmit' button to the job details page
  - Will immediately submit a new job with exactly the same inputs
    as the job being resubmitted.
  - Effectively, this is the same as copy -> submit, but it's one less
    click and browser render
  - The main benefit of this feature is for UI inputs that cannot be
    copied easily (e.g. SQL inputs) or massive job requests that take
    the browser a long time to render
- Added an 'elapsed' time field into the job details page
  - Counts the total time elapsed between when the job was submitted
    and when it reached a terminal state (finished, cancelled, error)
- All timestamps in the job details page now dynamically update
- (devs): refactored UI code
