Fix null-safety crashes in location/weather services (#932)

* Implement a graceful UI fallback when system ringtones are unavailable on iOS

* fix(android): remove null-unsafe unwraps in location/weather services

Resolve crash-prone null assertions in LocationFetcherService and WeatherFetcherService with guarded parsing, logging, and graceful exits.\n\nCloses #931

* fix(android): make foreground start API-safe for minSdk 24

Use SDK-gated foreground service startup to avoid 3-arg startForeground on older Android versions.\n\nRefs #933
