preservation coverage updates (first round)

- new by-year chart with stacked histograms of all 4 preservation
  statuses
- new-style single progress bar showing overall preservation status
- new by-volume query and chart

Old endpoints are left as-is, with the intention of having them
"deprecated" for some time span until entirely removing them.
