fix: auto-add to Bring! items running out within 7 days

- autoAddCriticalItems now adds:
  - critical: always (unchanged)
  - high: always (removed sub-conditions — PHP already gates high urgency strictly)
  - medium + days_left <= 7 + uses_per_month >= 3 (NEW: weekly depletion rule)
- Reduce auto-add guard from 10 min to 5 min for faster detection
- Covers: Latte di Montagna (high, 3gg), items running out mid-week (medium, 4-7gg)
