fix(ux): banner aperto senza 'Usa comunque'/'Ignora'; preloader ruota 3D; config default non bloccante

Banner prodotti aperti:
- Rimosse le opzioni 'Usa comunque' e 'Ignora' (non hanno senso
  se il prodotto è solo aperto — rimangono solo 'L\''ho finito!',
  'L\''ho buttato', 'Correggi data')
- Per prodotti scaduti non aperti il comportamento rimane invariato

Preloader startup check:
- Sostituito il mini-label monospace con una ruota 3D (stile cooking wheel)
- Testo grande, colorato: VERDE=ok, ARANCIONE=warning, ROSSO=errore
- Il check precedente sale in cima (rotateX tilt, dimmed) mentre il
  nuovo entra dal basso con animazione 3D
- setProgress() ora guida la ruota; slowAnim() aggiorna solo la barra

Defaults / non-bloccante:
- Gemini API key non impostata → ok:true 'non configurata' (verde)
- Bring! token non ancora generato → ok:true (verde, auto-generato al 1° accesso)
- La configurazione mancante mostra ✅ informativo, non ⚠️ warning
