Make nav3 entryprovider generic

[xephosbot]

The current implementation does not allow using koinEntryProvider when the backstack items type is not Any.
As a result, it’s necessary to manually cast the returned value:

NavDisplay(
    backStack = navigator.backStack, //List<MyNavKey>
    ...
    entryProvider = koinEntryProvider() as (MyNavKey) -> NavEntry<MyNavKey>
)

This PR removes that limitation and allows koinEntryProvider to work with typed backstack.

Pull request overview

This PR makes the EntryProvider type and related functions generic to improve ergonomics when using typed navigation backstacks with Navigation3. Previously, users had to manually cast koinEntryProvider() when working with typed backstacks (e.g., List<MyNavKey>), which was verbose and error-prone. The changes add a generic type parameter <T : Any> throughout the API surface.

Key Changes:

• Made EntryProvider typealias generic: EntryProvider<T> = (T) -> NavEntry<T>
• Added generic type parameters to koinEntryProvider, Scope.getEntryProvider, and Android-specific extension functions
• Added import for EntryProviderScope to support the cast needed for backward compatibility with the non-generic EntryProviderInstaller

The unsafe cast to EntryProviderScope<Any> is necessary due to the design where EntryProviderInstaller is hardcoded to EntryProviderScope<Any>. While this works because the navigation3 library's type-safe entry<T> calls handle type matching at registration time, it means that the generic type parameter T on koinEntryProvider<T>() doesn't actually provide compile-time type safety - it only affects the return type signature.

This could be misleading to API consumers who might expect that calling koinEntryProvider<MyNavKey>() would restrict entries to only those registered for MyNavKey. Consider adding a KDoc note explaining that T is a convenience type parameter for the caller's type system and doesn't enforce which entries are included at runtime.
