feat(cdm): add per-track quality-based CDM selection during runtime DRM switching

Browse Source 
Enable quality-based CDM selection during runtime DRM switching by passing track quality to get_cdm() calls. This allows different CDMs to be used for different video quality levels within the same download session.

Example configuration:
  cdm:
    SERVICE:
      "<=1080": wv_l3_local     # Widevine L3 for SD/HD
      ">1080": pr_sl3_remote    # PlayReady SL3 for 4K
