Summary

Routes app-module ViewModel retrieval through the local wireViewModel boundary instead of importing hiltViewModel directly at screen call sites.

This is a mechanical app-layer cleanup step toward isolating Hilt usage behind Wire-owned APIs before replacing the underlying implementation with Metro.

Changes

• Replaced app-module hiltViewModel(...) call sites with wireViewModel(...).
• Replaced direct Hilt ViewModel imports with com.wire.android.di.wireViewModel.
• Left the actual Hilt bridge centralized in AssistedViewModelExt.kt.
• Kept feature modules unchanged to avoid introducing illegal module dependencies.
