Convert ~45 remaining classic-only histograms to dual-format (classic + native) by adding NativeHistogramBucketFactor, NativeHistogramMaxBucketNumber, and NativeHistogramMinResetDuration fields. This follows the same pattern already established for ~11 histograms in the codebase. Signed-off-by: Charlie Le <charlie_le@apple.com>

| * [ENHANCEMENT] Distributor: Add `WrappedHistogram` with configurable size limit (`-validation.max-native-histogram-size-bytes`) to cap native histogram protobuf size before unmarshalling. #7570 | ||
| * [ENHANCEMENT] Ingester: Add lazy regex evaluation on head postings cache miss. Defers expensive regex matchers on high-cardinality labels to per-series filtering when a selective equality matcher already narrows the result set. Configured via `-blocks-storage.expanded_postings_cache.head.lazy-matcher-max-cardinality` (disabled by default). #7553 | ||
| * [ENHANCEMENT] Ring: Add ring metric to count number of duplicate tokens. #7626 | ||
| * [ENHANCEMENT] Metrics: Add native histogram support to all remaining production histograms, enabling dual-format (classic + native) exposition across all Cortex components. |
