feat: add Face bbox and Pose indicator to VideoPlayer

Features:
- Face bbox overlay with identity label
- Pose indicator (top-right corner)
- Extended loadProcessorMarks for all processors
- ASRX speaker:text format

Overlays:
- OCR: orange bbox + text label
- Face: blue bbox + identity name
- Pose: purple indicator badge

New props:
- showFace: boolean
- showPose: boolean

Data formats:
- Face: { frames: [{ frame, faces: [{ bbox, identity_name }] }] }
- Pose: { frames: [{ frame, pose }] }
- ASRX: { segments: [{ start_frame, end_frame, speaker, text }] }
