chore: remove Branch.io SDK and route deep links through own domain

Branch.io was inherited from Nova Wallet fork but never configured.
Removed SDK integration, manifest intent filters, Gradle dependencies,
Dagger DI modules, and string resources. Deep linking now routes
exclusively through app.pezkuwichain.io with verified assetlinks.json.
