test: cover the auth menu view-model formatting helpers

Direct coverage for lib/ui/auth-menu-builder.ts (the last substantive
untested module in lib/), asserting text content with ANSI stripped so
the contract holds in both UI palettes:

- main-menu title version suffix with the v prefix added only when
  missing, env save/restored
- relative-time buckets (never/today/yesterday/Nd/Nw/locale date)
- account titles prefer email > label > id > generic, number by
  quickSwitchNumber, and strip ANSI escapes and control characters
  from identity fields so a hostile label cannot repaint the row
- search text joins lowercased identity fields plus the row number
- row colors highlight the current row unless disabled, then map by
  status; status badges carry their status label, unknown fallback
- hint lines: default field order, Status only when the badge column
  is hidden, configured statusline field ordering, rate-limited and
  quota-exhausted flags, empty when every field is hidden
- focus keys use the storage position for account actions and the
  action type for static rows
