Fix offline i18n tests: refresh semantics and complete Monitor catalogs

- Web docs test no longer passes the removed refresh argument.
- i18n messages tests assert that --refresh keeps existing values and
  that only keys listed in --refresh-keys are re-translated.
- Add the new Monitor keys to de, fr, it, pt, sk and sv.
