Fix podcast player stability, V4V payments, and Lightning address

- Add audio.load() reset to prevent cascading failures between episodes
- Add onPlaying event handler for reliable post-buffer playback in WebKitGTK
- Add 15s loading timeout with user-friendly error for broken audio URLs
- Fix V4V LNURL-pay: use Tauri HTTP plugin instead of CORS-blocked browser fetch
- Fix Podcast Index API: use Tauri HTTP plugin for V4V enrichment
- Fall back to Podcast Index enclosure URL when Fountain.fm CDN is broken
- Update Lightning address to jure@getalby.com (Alby cloud migration)
- Add broad HTTPS scope for LNURL-pay across Lightning providers
