fix: smarter proactive shopping list urgency

- PHP: predictive urgency block now scales by imminence:
  round(days_left) <= 3 → high, <= 7 → medium, <= 14 → low
  (was flat 'low' for any days_left <= 14)
- PHP: also upgrades existing 'low' urgency to 'high' when
  imminent depletion detected (round(days_left) <= 3, isFrequent)
- JS: autoAddCriticalItems now also adds:
  - high urgency items with pct_left < 20% (nearly empty)
  - high urgency items with days_left <= 3 (imminent)
  - any item with days_left <= 2 and uses_per_month >= 5

Result: Latte di Montagna (27.8x/mo, 3 days left) now appears
on shopping list before running out, as do Lenticchie/Riso
Basmati at 1% stock and Sandwich at 1 day left.
