The GET body cache exports 11 `rustfs_object_data_cache_*` metrics but no
bundled dashboard visualized them. This adds one so operators can see the
cache's behaviour without hand-writing PromQL.
New `grafana-object-data-cache.json` (auto-provisioned from the dashboards
directory, `${DS_PROMETHEUS}`, schema 38) with 19 panels covering every metric:
hit ratio and lookup outcomes, plan decisions and cacheable ratio, fill
outcomes and fill-duration quantiles, hit-vs-fill byte throughput, entries and
weighted bytes vs capacity, in-flight fills, memory-pressure skips,
invalidations by reason/outcome, and size-class breakdowns. PromQL matches each
metric's type — rate() for counters, histogram_quantile() for the fill-duration
histogram, direct reads for gauges.
The observability README (EN + ZH) dashboard table gains a matching row.
