chore(deeplink): integrate deep link handling into app lifecycle

Wire up deep link infrastructure with app initialization and event handling.

Backend Integration:
- Register deep link module and commands in mod.rs
- Add URL handling in app setup (src-tauri/src/lib.rs:handle_deeplink_url)
- Handle deep links from single instance callback (Windows/Linux CLI)
- Handle deep links from macOS system events
- Add tauri-plugin-deep-link dependency (Cargo.toml)

Frontend Integration:
- Listen for deeplink-import/deeplink-error events in App.tsx
- Update DeepLinkImportDialog component imports

Configuration:
- Enable deep link plugin in tauri.conf.json
- Update Cargo.lock for new dependencies

Localization:
- Add Chinese translations for deep link UI (zh.json)
- Add English translations for deep link UI (en.json)
