Lutz Finsterle db46fcf0c6 Add SG-Ready startup grace period and daily PV yield tracking ...

SG-Ready startup grace period (sg_ready_startup_min: 10):
Heat pump compressor takes ~9 minutes to start after receiving the
SG-Ready signal. Previously, idle detection fired after only 3×2min=6min,
turning off SG-Ready before the compressor had time to respond. The grace
period suppresses idle detection for the configured duration after activation.
0 = disabled (tests and unconfigured deployments are unaffected).

Daily PV yield (photovoltaic_production_cumulated_currentDay):
Reads actual kWh produced today from Prometheus (Wh → kWh, ÷1000).
Logged as pv_today_kwh each cycle. Shown on status page in two places:
- PV card sub-line: "Heute: 31.9 kWh"
- Forecast card alongside forecast: "Ist: 31.9 kWh"
Immediately makes forecast vs reality visible (today: forecast 15.9,
actual 31.9 kWh — explains why SOC bypass triggered).
