Add paste-your-songs manual import feature

Users can now paste a list of songs as text to create a playlist without
needing any service integration. Supports multiple formats: "Artist - Title",
"Title by Artist", "Artist: Title", and numbered lists. Includes a live
song count preview in the modal and free tier playlist limit enforcement.
