Context menu opens twice as slowly on iOS compared to Android

Description

From #4594

There is a significant difference in the interface's response time when opening the context menu for a Point of Interest (POI) between the iOS and Android versions. On iOS, the delay before the menu appears is noticeable to the user, making interaction with the map less smooth. On Android, the same menu opens almost instantly

Steps to reproduce

Open OsmAnd on iOS and Android devices > Tap an object to bring up the context menu > Compare the time from when you tap until the menu panel with information about the object fully appears

Actual result

On iOS, the context menu opens about twice as slowly as on Android. This delay occurs both when opening the menu for the first time and when reopening it for different items

Expected result

• The speed at which the context menu opens on iOS should be optimized to match that of the Android version, ensuring that the interface responds instantly to user touch

Your Environment

By optimizing the nearestPoi processing, the contextual menu opening time was reduced by approximately 0.2–0.3 seconds.
