Remove kg/l units everywhere — only g (grammi) and ml (millilitri)

- HTML: removed kg/l options from all unit selector dropdowns
- JS detectUnitAndQuantity(): auto-converts kg→g (*1000) and l→ml (*1000)
- JS unit labels: removed all kg/l entries from unitLabels maps
- JS category defaults: frutta 1000g, verdura 500g, bevande 1000ml
- JS step/min logic: simplified for g/ml only (no more 0.01 steps)
- JS getSubUnitStep(): removed kg/l cases
- JS isLowStock(): removed kg/l threshold
- JS spec parser: labels now show g/ml instead of kg/L
- PHP recipe parser: converts kg→g and l→ml immediately on parse
- PHP AI prompt: updated to specify only g/ml/pz/conf units
- PHP migration endpoint available at ?action=migrate_units (no-op if DB already clean)

Esempio: se in dispensa c'è "Farina: 1000 g" e la ricetta richiede 200g, qty_number = 200. Se "Riso: 2 kg" e servono 300g, qty_number = 0.3. Per ingredienti non dalla dispensa, qty_number = 0.
+8. IMPORTANTE - QUANTITÀ NUMERICHE: per ogni ingrediente dalla dispensa, il campo "qty_number" DEVE contenere il valore NUMERICO da scalare dall'inventario, espresso nella STESSA unità di misura della dispensa. Le unità ammesse sono SOLO: g (grammi), ml (millilitri), pz (pezzi), conf (confezioni). NON usare mai kg o litri. Esempio: se in dispensa c'è "Farina: 1000 g" e la ricetta richiede 200g, qty_number = 200. Se "Riso: 2000 g" e servono 300g, qty_number = 300. Per ingredienti non dalla dispensa, qty_number = 0.
 9. GESTIONE SMART QUANTITÀ: NON lasciare rimasugli poco usabili in dispensa. Se un ingrediente ha una quantità piccola (es. 50g di formaggio, 1 uovo, 100ml di latte), preferisci usarlo TUTTO piuttosto che lasciarne una quantità inutilizzabile. Se invece la quantità è abbondante, usa solo il necessario lasciando abbastanza per un altro pasto. Pensa sempre: "quello che resta sarà sufficiente per un altro utilizzo?"
