acceptance: replace TestGenerateFromExistingJobAndDeploy

[shreyas-goenka]

Moves TestGenerateFromExistingJobAndDeploy from integration/ to acceptance/. Acceptance tests are the only path that wires up terraform installs now, so the integration variant can't run end-to-end.

The new test runs the same flow (upload notebook → create job → bundle generate job → bundle deploy → bundle destroy) on both modes:

• localupdate: ~5s
• cloudupdate (azure-prod-ucws, terraform + direct): ~3-4m

This pull request was AI-assisted by Isaac.

We did not have coverage for generate + deploy in our existing tests, that's why I translated it instead.
