chore: reconcile the JxnLexn merge wave with the release tip (#13921)

Lands the combined-board reconciliation of today's JxnLexn wave as one follow-up: i18n fill for #12471/#13555's new keys (real vi translations), free-tier count 446→452, file-size rebaseline for #13556. check-new-key-coverage PASS; only the three pre-existing file-size reds remain.
