Port #1292 to dtq-dev-9-base: UFAL/Separate CLARIN license payload from sections.license (#1497)

TESTS-ONLY completion of the #1292 port. The runtime hunk (the CLARIN license
section PATCHes /sections/clarin-license/select instead of sections.license)
arrived with the v9 squash, and the karma spec that pins the PATCH path arrived
with #1396 (card FE-25) - section-license.component.spec.ts already asserts
body[0].path === '/sections/clarin-license/select'. Nothing to add there.

What was still missing is the e2e half. #1292 also hardened
cypress/e2e/submission-ui.cy.ts so that the CLARIN licence section's card
header is asserted to carry the green status icon (.fa-check-circle.text-success,
15 s timeout) when no file has been uploaded. That file does not exist on the v9
base - the fork's submission-ui.cy.ts was replaced by the vanilla
submission.cy.ts - so the step is adapted into submission.cy.ts instead.

v9 notes:
- The step is conditional on div[id="section_clarin-license"] existing (decision
  D-03). CI e2e runs against a vanilla backend image, which does not ship the
  clarin-license submission step, so an unconditional step would fail there. On a
  CLARIN backend the section is present and the assertions run.
- It is placed in the first test ("should create a new submission when using
  /submit path"), which uploads no file - the same precondition as the fork's
  "should not show validation warnings when no file is uploaded (metadata-only)"
  test the hunk came from.
- The fork's cy.wait(1000) settle and the 15 s retry timeout are kept verbatim.
- No cy./expect() step is removed or weakened (guard X6).

Card PB-08 (tranche T3).
