Carica lista: auto-detect URL list vs tracklist

Adesso 'Carica lista' nella tab Scarica riconosce automaticamente
il formato del file .txt:

- Se la prima riga e un URL (http/https) -> URL list (come prima)
- Altrimenti -> tracklist parsata 'Artista - Titolo (variant) (durata)'
  e scaricata cercando ogni brano su YouTube (riusa download_playlist)

Parser robusto: gestisce numerazione iniziale (1. / 1) / 1: / 1-),
qualsiasi tipo di dash (-, en-dash, em-dash, ...) e durata finale
'(M:SS)'. Testato sulla Beatport Top 100 Melodic House & Techno
(100/100 tracce parsate).

api/bridge.py: nuovo start_tracks_download, load_url_list ritorna
'kind: urls|tracks'.
webui/js/app.js: badge cambia tra 'X URL' e 'X tracce', avvio
chiama start_tracks_download quando appropriato.
