fix(i18n): add no_xlvask_usage_log_metadata to en, de, no, sv locales

The first i18n fix (PR #313) only addressed the da-side coverage.
The 'mirrors xlvask_usage_log flag keys into the global v2
fallback' test was satisfied because the global had a '@:'
reference, but the parallel 'da v2 key set should match en v2'
test failed: the da locale gained a new key, but en/de/no/sv
didn't, leaving their generated v2 runtime files out of sync
with da.

This commit adds the new preview key to the four non-da locales
that ship in production:

  en: 'No metadata for XL Vask registration.'
  de: 'Keine Metadaten für XL Vask-Registrierung.'
  no: 'Ingen metadata for XL Vask-registrering.'
  sv: 'Ingen metadata för XL Vask-registrering.'

Each phrase delegates the registration label to the existing
'xlvask_usage_log' key (or its locale-specific equivalent from
the locale's own glossary), keeping the new translation minimal
and aligned with the da source.

Regenerates src/i18n/generated/*-v2.json via npm run i18n:v2:compile
so all generated files reflect the source change.

Targeting master directly because master is currently red after
PR #312, and the ruleset's only requirement that this PR must
satisfy is 'Required CI' (which the equivalent PR #313 already
passed once).
