Ovidiu U 8e29980dfe perf: memoize PriceReliability + PriceClassification per row ...

Audit item #10. PriceReliability::fromUpdatedAt was being invoked
~10× per station per /api/stations response — twice in the sort
comparator (once for $a, once for $b), once in the count groupBy, and
once per resource render. PriceClassification::fromUpdatedAt was
called twice inside the resource (value + label).

The controller now computes the parsed datetime + reliability +
classification once per row and stashes them on the row. Sort,
groupBy, and StationResource read the cached values; the resource
keeps a fresh-compute fallback for callers that bypass the controller.
