Added checks if style is fully loaded before accessing it

[albertmoravec]

Added missing checks which caused crashes in certain situations on Android.

This is probably an issue on iOS as well, but I don't have access to my Mac at the moment. I'll open a separate PR for iOS if I am able to confirm and fix this.

@albertmoravec Can you describe these "certain situations"? Maybe I can reproduce them on iOS.

Ah, I did not have much time to check myself, but generally you can break a lot of things by changing map style (e.g. between normal and satellite map) and doing other stuff like clicking into the map while it is loading. At least that's how I triggered this on Android.

The map tends to break a lot when you put all its features under stress when style is loading, since a lot of places are missing necessary checks and that breaks Flutter a bit more than for native apps.

Pull Request Overview

This PR adds null safety checks to prevent crashes on Android by ensuring the map style is fully loaded before accessing its layers. The changes address situations where style operations were attempted before the style finished loading.

• Added style.isFullyLoaded() checks alongside existing null checks
• Applied the fix to two methods that access style layers
