Cherry-pick and integrate playlist import from playlist-import-impl branch:
- Add playlist_import Rust module with providers (Spotify, Apple, Tidal, Deezer)
- Add track matching algorithm (ISRC first, then fuzzy matching)
- Add PlaylistImportModal.svelte with progress log UI
- Wire up import button in Sidebar
- Add modal state management in uiStore
- Register Tauri commands for preview and execute
Original implementation by Codex, integrated manually due to branch divergence.
