Improve status page ergonomics

- WW card shows current tank temperature (Speicher: 48.7°C)
- SG-Ready card shows inline compressor power (Kompressor: 1.5 kW / Standby)
- Consumer reason text now wraps instead of being silently truncated
- Add readiness hints on inactive wallboxes: explains what's blocking
  activation (SOC too low / forecast insufficient / waiting for PV ≥ Xw)
- Add WW readiness hint when forecast is below threshold
- Move Monitor-Only toggle button to header (next to timestamp) for
  symmetric placement with the resume button in the monitor banner
- Remove charging advice card (outdated for proactive charging logic)
- Remove compressor power footnote from page bottom (now inline in card)
