Fix issues in the release build related to Navigation Component

[AdamGrzybkowski]

Description

Two things are broken in the release build:

1. The back navigation after login/logout is wrong. The app should close rather than go back to the login screen and vice versa.
2. The selected tab's icon on the bottom nav bar is tinted.

The root cause is the usage of ::class.qualifiedName when comparing the current navigation destination. With r8 in the release build, the code is obfuscated, and the name of the RootDestination or HomeDestination is different.

This PR fixes this issue by using the API function from the Navigation library hasRoute.

Fixed issue number 1:

Screen_recording_20250812_112707.mp4

and the icon tinting:

Testing Steps

1. Install the release build - you can do it from the Android Studio by changing the buildType to release. (Make sure you have the mobile secrets updated and applied to the project)

2. Log in
3. Log out
4. Use the system back button
5. Confirm the app is closed
6. Open the app again
7. Log in
8. Confirm the icon of the selected tab in the bottom bar is tinted

Pull Request Overview

This PR fixes navigation and UI issues in the Android app's release build caused by code obfuscation. The main problem was using ::class.qualifiedName for route comparison, which fails in release builds where class names are obfuscated by R8.

• Replaces ::class.qualifiedName route comparison with Navigation library's hasRoute API
• Fixes back navigation behavior after login/logout operations
• Resolves bottom navigation bar icon tinting issues
