Fix backfill page missing partitioned table stats, fix contacts map init

Backfill page now sums child partition stats for partitioned tables
like hrrr_profiles (relkind 'p') which were excluded by the relkind
'r' filter. Contacts map defers Leaflet init to requestAnimationFrame
so the flex container has dimensions before map initialization.
