/**
 * Regression guard for #6290.
 *
 * On the provider detail page the connection-status filter labels
 * (`providers.filterAll/filterActive/filterError/filterBanned/filterCreditsExhausted`)
 * rendered as `__MISSING__:All`, `__MISSING__:Active`, ... for non-English
 * locales. The keys existed in the correct `providers` namespace in en.json,
 * but the locale mirrors carried the `__MISSING__:` sentinel (or omitted the
 * key entirely) — mirror translation debt, not a namespace mismatch.
 *
 * Every shipped locale under src/i18n/messages/ MUST have a real, non-sentinel,
 * present value for these five keys.
