New POST /event/{id}/test-lpr endpoint runs PlateRecognizer on the full
frame and local OCR on the drawn bbox region (with perspective correction
when possible). Annotation UI shows results inline with a one-click
"Utiliser" button to copy the best plate into the input field.

Canvas now uses img.naturalWidth/Height as its coordinate space
so zooming in shows actual 4K pixels instead of upscaled 800px.
CSS width/height handle display scaling separately.
Replace window.open() fullres button (blocked by popup blockers)
with a direct <a target="_blank"> link updated on frame select.

Annotation canvas:
- Mouse wheel: zoom centered on cursor (1×→20×)
- Right-click drag or Space+drag: pan
- Two-finger pinch-to-zoom on touch devices
- Bbox coordinates computed in logical image space (zoom-invariant)
- "Plein écran" button opens current frame in new tab at full res
- Zoom % indicator + reset button
Event detail lightbox:
- Mouse wheel: zoom in/out (0.5×→20×)
- Drag to pan when zoomed in
- "Ouvrir en plein écran" link opens raw frame at native 4K in new tab
- Zoom resets on image change or lightbox close

New page /event/{id}/annotate:
- Frame selector grid (all frames from the event)
- Canvas with click-and-drag rectangle drawing to mark the plate bbox
- Touch support for tablets
- Plate text input (pre-filled with auto-detected plate)
- Saves image + YOLO label (.txt) + plates.csv to /data/annotations/
- Stores annotation metadata in DB (annotations table)
/dataset/export serves a ZIP with images/, labels/, plates.csv and
a data.yaml ready for YOLOv8/v9 fine-tuning on Google Colab.
"Annoter" button added to event detail header.
