feat(phase5): stream editor, i18n, settings, key management

- StreamEditor: view/add/trim/delete entries with field management
- KeyDetail: TTL editor dialog, rename dialog, copy key name button
- i18n: English + Chinese locale system with composable
- SettingsView: theme selector, language switch, scan count, font size
- MainArea: added Settings tab
- RedisService: stream/rename/exists operations
- Preload: stream/rename/exists IPC channels
