Rename noChildren to hasChildren for clarity

[gioalex07]

The property noChildren returned true when children were present, which was semantically misleading. Renamed to hasChildren to match the actual behavior and avoid confusion for future contributors.

Summary

• Rename WiFiDetail.noChildren to hasChildren for semantic clarity.
• The property name was misleading: noChildren returned true when children were present.

What does this implement/fix?

• Renamed property in WiFiDetail.kt
• Updated consumer in AccessPointsAdapterGroup.kt (2 call sites)
• Updated test names and assertions in WiFiDetailTest.kt and AccessPointsAdapterGroupTest.kt

Does this close any issues?

• N/A (naming/clarity improvement)

How was this tested?

• Platform: WSL2 / AlmaLinux 9
• Build variant: debug
• Commands run:

./gradlew ktlintCheck     → BUILD SUCCESSFUL
./gradlew testDebugUnitTest → BUILD SUCCESSFUL

Thanks for the contribution.

1. AI Usage Disclosure
   Disclose any AI tool involvement and use the “AI assistance used” label.

2. Testing Requirements
   Changes must be tested on a real Android device.
   Emulator‑only testing or running build tasks (e.g., ktlintCheck, unit tests, successful Gradle build) is not sufficient.
   UI/UX behavior, layouts, gestures, and rendering often differ between emulators and actual devices.

Please update the PR with real‑device testing details so review can continue.

Thank you for the contribution.
The CI pipeline is failing because this change reduces code coverage.
The project requires that coverage does not decrease, so additional unit tests are needed for the new or modified logic.
Please update the PR with the necessary tests so the coverage check can pass.
