* ci(i18n): fail on new English-identical translations
The drift check only warned about locale values identical to English, so
untranslated strings kept landing. It now fails on any such value that
tools/i18n/identical-en-baseline.json does not record for that locale and
key. The baseline captures today's 2,015 entries: legitimately identical
values (brand and technical names, language autonyms, PIN) and the
existing debt. An entry only covers the English text it recorded, so
copying reworded English into a locale fails too.
Baseline entries that are no longer identical are reported, not fatal.
`pnpm run i18n:baseline:update` rewrites the baseline deliberately; CI
runs `pnpm run i18n:validate` (node tests, then the check) and never
rewrites it. `--fail-on-identical` remains as a strict audit.

* fix(i18n): keep the baseline intact on failed updates and strict audits
`--update-baseline` now writes nothing while any locale is unreadable or
has missing or extra keys, so an incomplete translation cannot reshape
the baseline. `--fail-on-identical` no longer reads the baseline it
ignores, so a damaged file cannot block a strict audit.
