Normalize layout padding shorthands

[MihaiCristianCondrea]

Summary

• replace paired top/bottom padding with android:paddingVertical on scroll containers to cut redundant attributes
• switch symmetrical margin and padding declarations to horizontal/vertical variants on chips, list sections, and binding text
• use layout_marginVertical on ad cards and bottom sheet handle to reduce attribute count without affecting spacing

Testing

• ./gradlew test --console=plain (fails: SDK location not found in container)
