Locations store State as either a two-letter postal code or a full state name (the location list filter expands codes to both forms via UsStateCodes.ExpandStorageValues, and dev fixtures carry State = "indiana"). DashboardRegions.Resolve only matched the two-letter key, so every location stored as a full name fell into Unmapped/Other and the East/Central/West/ California bars undercounted. Normalise the stored value through a new UsStateCodes.ToCode, which accepts a code or a full name and returns the canonical postal code, before the zone lookup. Extend the region test with full-name storage forms and add an invariant asserting every US state and its full-name form resolves to a canonical bucket.
