Fix proactive charging, logging, and status page ordering

1. SOC high bypass: when SOC >= soc_high_bypass_pct (default 90%), activate
   car charging without requiring a good forecast. Solves today's missed
   charging window where 4kW was exported for 6h with a full battery because
   the intraday forecast dropped from 15.4 to 13.3 kWh.

2. Log ambient_c in every cycle: makes it diagnosable why isHeatingPeriod
   suppresses SG-Ready on warm days (heating_min_ambient_c: 15°C gate).

3. Consumer names in logs: replace slog integer Consumer values with
   .String() so logs show "wallbox_a" instead of "2".

4. Status page order: reorder consumers by EMS priority (WallboxA →
   WallboxB → WW → SG-Ready) instead of the old reversed order.
