feat: expand DRM playback and discovery support

- native FairPlay HLS playback added for iOS/Safari with same-origin license proxy
- Widevine license proxy added to avoid browser-side CORS license failures
- DRM-specific playback URLs added for per-browser MPD/HLS variants
- admin DRM auto-discovery added for DASH Widevine and HLS FairPlay manifests
- DRM stream probing now checks DRM-specific playback URLs
- Shaka quality selector deduplicates audio variants while preserving same-resolution bitrates
- DRM proxy source and config index matching stabilized after source reordering
- DRM manifest discovery rejects private, loopback, link-local, and redirect targets
- Android Telegram WebView Widevine handling now probes key-system capability before blocking
