Add PTZ calibration app and calibrated move parameters

[MateoLostanlen]

• Add tools/ptz_calibration_app.py: a Streamlit app for calibrating PTZ camera parameters (speed/bias per axis, FOV per zoom level via QR-code chained-ratio method)
• Update pyro_camera_api/pyro_camera_api/api/routes_control.py with calibrated values for both reolink-823S2 and reolink-823A16:
  • Pan/tilt speed and bias tables (open-loop move model: T = (target° - bias) / ω)
  • Per-adapter measured FOV lookup tables (42 entries, zoom 0–41) replacing the inaccurate model-based formula
  • _pick_speed() helper to select optimal speed level for a target displacement
  • POST /click_to_move endpoint: click a pixel in the image, camera pans/tilts to center on it

Calibration app features

• Live View tab: capture, zoom, manual move
• Click-to-Move tab: click on image to move camera, with before/after comparison
• Zoom FOV tab: step-by-step QR-code-based FOV measurement with auto-retry, bridge support for QR repositioning
• Calibration tab: impulse-response measurement (move at known speed/duration, measure pixel displacement)
• Results & Export tab: linear regression of speed/bias, export to JSON
• Presets tab: PTZ preset management
