test(cli): ledger the plugin-dev i18n loss so the fix has something to check against (#15232)

The row added in the previous commit went RED naming a subsystem the ledger
does not carry — the exact failure #15004 exists to make loud:

  B2 · plugin-dev I18nServicePlugin auto-detect over the caller-supplied
  stack · translations

This records it, which turns the pin green at 25 rows and makes the loss a
measured fact rather than an argument. The next commit fixes the reader and
deletes this line again, so `OPTION_B_LOSSES` ends this branch exactly as it
started it — the ledger never grows.
