// The dashboard tier filter (batch 3) folds every raw account tier into exactly
// four buckets — pro / free / unknown / expired — so the filter dropdown and the
// per-tier counts (getAccountListStats().byTier) stay closed over a known set.
// Any paid-ish tier (enterprise / teams / trial / premium / …) reads as "pro";
// empty or unrecognized reads as "unknown". Keep in sync with setAccountTier's
// manual whitelist.
