feat(web): anteprima edge sul modello + tracker pulizia rumore + UCS baricentro

Pannello "🔬 Anteprima edge / pulizia rumore" sotto il canvas modello.
Permette tuning interattivo dei parametri di selezione edge per
togliere "sporcizie" (rumore di sfondo, edge spuri) prima di
trainare il matcher.

Server:
- POST /preview_edges: dato modello+ROI+param edge, ritorna immagine
  ROI con overlay:
  * heatmap magnitude gradient (sfondo)
  * verde scuro: pixel sopra hysteresis edge
  * cerchietti colorati per bin: feature scelte (palette 16 bin)
  * UCS rosso/verde sul baricentro feature (richiesta utente):
    asse X destra, Y giu' (image y-down)
  Ritorna anche stats: n_features, n_edge_strong, percentili magnitude,
  ucs_baricentro {cx, cy}

UI:
- Slider weak_grad/strong_grad/num_features/spacing + checkbox polarity
- Re-fetch debounced (200ms) ad ogni input → preview live
- Bottone "Applica ai parametri Avanzate": copia i valori scelti
  nei campi Avanzate del matcher principale
- Auto-fetch quando il pannello viene aperto

Use case: operatore vede SUBITO quali edge il matcher userebbe,
regola soglie per escludere rumore, applica e poi MATCH.
