feat(ecstore): expose read version stage metrics (#6073)

Browse Source 
Record local read_version path resolution, path length check, xl.meta read, and metadata decode durations through the existing GET stage metrics channel. The new samples are gated by GET stage metrics so metrics-off reads avoid timer and recorder work.
