In Hermes release builds, useEffect captures closure values from the first
render. If instanceUrl or token were empty at that moment (before SQLite reads
complete), no fetch ran and map/graphs never loaded. Adding them to the
dependency array ensures the effect re-runs once the values are available;
guards on existing geojson/timeseries state prevent double-fetching.
Also add @maplibre/maplibre-react-native to the Expo plugins array so that
expo prebuild applies the library's required Gradle property configuration to
the Android project.
