Arricchimento calcio: ricerca web AI, filtri avanzati, log

Aggiunto arricchimento automatico delle partite calcio tramite ricerca web AI (SearXNG, Bing, Google, SerpAPI) con risultati inseriti nel CSV. Introdotta la classe WebSearchClient multi-provider e le relative opzioni configurabili (provider, chiave, lingua, max risultati, delay). Migliorata la UI con filtri orari, filtro avanzato per nazione/lega e pannello di configurazione ricerca web. Estese le impostazioni (AppConfig, UserSettings) per supportare i nuovi parametri. Introdotto logging avanzato file-based (AppLogger) con livelli di severità e rotazione giornaliera. Migliorata la gestione errori API e la UX nella selezione filtri e provider.
