imSp4rky 4422c975c3 feat(drm): add FairPlay->PlayReady bridge for cbcs HLS ...

FairPlay HLS (SAMPLE-AES/cbcs) ships a content KID in its skd:// key but no PlayReady/Widevine PSSH. Synthesize a PlayReady header from that KID so a PlayReady CDM can license and decrypt it whenever the backend is multi-DRM.

- FairPlay DRM (PlayReady subclass) + FairPlay.from_kid; fairplay_kid_from_skd extracts the KID from GUID / ?KID= / 32-hex skd forms (core/drm/fairplay.py)
- build_pr_header_from_kid synthesizes a WRMHEADER/PRO (cbcs->AESCBC v4.3, cenc->AESCTR v4.0); PlayReady.from_track falls back to a tenc KID when no PSSH
- Service.get_fairplay_license hook (defaults to get_playready_license)
- dl.py routes FairPlay tracks to get_fairplay_license through the PlayReady CDM
- EXAMPLE service + config.yaml document the bridge end to end
- tests for the synthesized header and skd KID extraction
