What's new

Migrates ViewModel creation to Metro/MetroX.

This introduces shared Metro-backed ViewModel factory/bindings and updates app, Cells, and Meetings ViewModel call sites to resolve ViewModels through Metro-backed APIs.

Why

This moves us closer to the final Metro DI model where ViewModel construction is handled by Metro scopes instead of Hilt-style/manual bridge objects.

The important part is scope-safe ViewModel lookup. Session ViewModels must include the current session/account scope in their key, otherwise Compose can reuse a ViewModel created for another account after account switching, logout, or client removal.

Changes

• Added shared Metro ViewModel factory wiring.
• Added app-level ViewModel bindings.
• Added Cells and Meetings ViewModel bindings.
• Added scopedMetroViewModel and scopedAssistedMetroViewModel helpers with KDoc.
• Updated ViewModel helper functions to use Metro/MetroX with scoped keys.
• Preserved special auth key handling for login/remove-device flows that use route args or ViewModelStoreOwner.
• Included feature module ViewModel binding containers in the root WireApplicationGraph, so the app-level MetroViewModelFactory can resolve Cells and Meetings ViewModels.
