feat: real ECG/Pleth waveform streaming + clinical monitor UI redesign

- schemas.py: Add ecg_wave and pleth_wave List[int] fields to NormalizedVitals
- contec_parser.py: Extract raw 8-bit waveform samples from binary packets
  - 286/288-byte (Subtype 21): bytes[8..263] = Pleth waveform (256 samples)
  - 989-byte (Subtype 20): bytes[8..903] = ECG waveform, downsampled 4x -> 224 pts
- dashboard.html: Full clinical monitor redesign
  - Scrolling sweep waveform engine (ECG green, Pleth cyan, Resp amber)
  - Real samples fed from WebSocket ecg_wave / pleth_wave arrays
  - Synthetic fallbacks when no live data
  - Right panel: HR, SpO2, RR, NIBP, Temp with range badges
  - MRN-only verification overlay
  - Minimal-mode support for iframe embedding
