Implement full NFC-URL streaming architecture

- rc522: add NDEF URL reading via WUPA+cascade anticoll+SELECT+TLV parse
- AudioPlayer: route http:// URIs to esp_player_http_music_play()
- CacheManager: download URLs async to /sdcard/cache/{hash}.{ext}
- TagPlayerControl: NDEF URL → cache-or-stream; fallback to UID local mapping
- RFIDInterface: wire ndef_callback, expose combined uid+url callback
- WebInterface: add /api/info, /api/storage, /api/playback, /api/bluetooth
- BluetoothInterface: stub for A2DP speaker mode
- Networking: WiFi connect with 30s timeout instead of blocking forever
- main.cpp: re-enable WiFi + web server, fix init order, add CacheManager
- www/: full SPA — playback controls, device info, storage, BT pairing
- .gitmodules: switch rc522 submodule URL to HTTPS
