fix(cypress): stabilize submission & admin-workflow specs on slow CI

These VSB/CLARIN pages render slower than Cypress' 4s default, which
caused the last two failures after the login fix:

- submission: the CLARIN submission form loads several controlled
  vocabularies before the metadata fields appear, so input#dc_title was
  not yet in the DOM. Wait for ds-submission-edit and give dc_title a
  generous timeout. After a failed deposit the metadata accordion section
  can collapse (ngb-accordion drops its body), so re-expand it before
  asserting the title field is invalid.
- admin-workflow: the supervision-configured search can take a while to
  return on a freshly started backend; allow extra time for the first
  list-object to render.
