Batch 2 of the locale expansion across the dashboard catalog, docs mirrors, CLI catalog, README, locale index and the site. 51 → 59 locales.
Also: the translator restores the ICU literal escape around angle placeholders, and the docs chunker splits oversized sections before translating.
⚠️ base-red inherited: #12732 — the eight red checks fail identically on unrelated PRs cut from the same base (e.g. #13197); every gate is green locally after merging the base.
Batch 1 of the locale expansion: Greek, Croatian, Serbian, Lithuanian, Estonian, Latvian, Slovenian, Maltese and Irish across the dashboard catalog, docs mirrors, CLI catalog, README, locale index and the site. 42 → 51 locales.

⚠️ base-red inherited: #12732 — the four unit shards and Fast Quality Gates fail identically on unrelated PRs cut from the same base.
