Previously aprsMapAddStation forced Leaflet map init on a hidden element
during history restore. When live packets later arrived they stamped a
fresh _tsMs, resetting the displayed age to "0s ago".
Decouple data storage from Leaflet rendering:
- aprsMapAddStation now stores station data in stationMarkers immediately
(with the original _tsMs from localStorage) without touching the map
- _aprsAddMarkerToMap creates Leaflet markers only when the map is ready
- initAprsMap materialises all buffered APRS entries on first open
