fix: add missing StateFlow import, merge duplicate KDoc blocks, and fix rebase conflicts

- Add missing 'import kotlinx.coroutines.flow.StateFlow' in SearchBarViewModel.kt
- Merge duplicate KDoc blocks on nameShowWithFallback in ElectrumXClient.kt
- Move NamecoinLookupException to ElectrumXServer.kt (avoid redeclaration)
- Remove duplicate NameShowResult/ElectrumxServer from ElectrumXClient.kt
- Fix ElectrumxClient -> ElectrumXClient renames in NamecoinNameService
- Extract namecoinElectrumxClient in AppModules.kt for NamecoinNameService.init()
- Update package paths from nip05.namecoin to nip05DnsIdentifiers.namecoin
