Redwally/Navikat ? reverse-engineered prompt

Build me a self hosted web app for managing music downloads into my Navidrome library.

I want to be able to search for tracks and playlists from Deezer, and Spotify too if I add my own credentials, then pick a result and have it download the audio from YouTube, tag it properly with album art, metadata, and synced lyrics, and save it straight into my music folder in a clean organized way. It should handle single tracks, playlist links, album links, direct YouTube URLs, and CSV imports from playlist export tools.

Please make it run nicely in Docker, use my host music folder, and trigger a Navidrome library rescan when downloads finish. I also want a visible queue with progress, pause and resume, cancel for single items or everything, and a simple review step when a match is uncertain. If it makes sense, add an optional password login, and look up current docs online if you need to.
