Link-only search for short song names

[NomadicDaggy]

Currently 1 or 2 letter searches take a good 10 seconds, so they should be disallowed to mitigate db overload. In place the user should be prompted to find the track on spotify and insert the spotify track link into spl.

On large screens the functionality is already there, we just need to catch the attempt and prompt for a proper retry.

On small screens however, the user can't drag and drop anything, so the search input field needs to accept a spotify track link, recognize it as such and query the api by track.spotify_id.
