Fix LibreTranslate timeout: increase wait to 3min, add Ansible healthcheck wait

- TranslateCommand: increase waitForApi retries from 30 to 90 (3 minutes total)
- Ansible deploy: add explicit healthcheck wait step (60×5s = 5min max) before translation
- First launch downloads ~2-4GB of language models, needs more time
