fix(wallet): resolve DI scope mismatch, WalletState constructors, packaging conflict

- CardanoWalletManager moved CardanoClient dep out of AppScope — was causing
  Metro MissingBinding at compile time (CardanoClient is SessionScope)
- refreshBalance() now takes balanceLovelace param instead of fetching from client
- WalletState constructor calls fixed with all required fields
- app/build.gradle.kts: added META-INF/gradle/incremental.annotation.processors
  to pickFirsts to resolve moshi-kotlin-codegen/lombok resource conflict
- App builds and launches successfully on emulator (verified)
