Map: loading indicator + reliable first-open centering
The map shows a "Loading history…" pill while activity pages are still streaming in. Map fitting is now race-proof: the first fit is instant and frames what the map actually shows — a featured or shared selection included — regardless of whether the map style or the data finishes loading first. Later fits animate to the full dataset and never override a selection you are presenting.
