Add calorimetric SCOP sensors with integration+utility_meter ...

- Add platform:integration sensors for thermal and electrical energy (W→kWh)
- Fix utility_meter sources to use integration sensors (not power sensors directly)
- Remove invalid unit_of_measurement from utility_meter entries
- Add SCOP dzienny/miesięczny template sensors
- Replace scop_pompy_sezonowy (wrong power_output_lo register) with
  scop_dzienny and scop_miesieczny (calorimetric, from utility meters)
- energia_cieplna_pompy_total: integrates moc_cieplna_pompy [W] → kWh
- energia_elektryczna_pompy_total: integrates moc_pompy_aktualna [kW] → kWh

Replace estimated COP with calorimetric COP for Sevra Split 8kW ...

Old formula: COP = 5.0 - (T1-T4)*0.05  (rough estimate, not a measurement)
New formula: COP = (flow_lh × 1.163 × (TW_out - TW_in)) / P_el

Where:
- flow_lh = water_flow_register × 22.1 L/h (derived from Sevra 8kW nominal 1370 L/h)
- TW_in/TW_out from RS485 registers
- P_el = outdoor_unit_current × outdoor_unit_voltage

Also added sensor.moc_cieplna_pompy [W] for thermal power output.

Note: SCOP from power_output_lo register is NOT thermal COP - it measures
compressor shaft power ratio, not heat output. Left as-is with comment.

Current result: COP=5.42 at T4=6°C, TW_in=27, TW_out=31, freq=57Hz (plausible)

Add grid export/import sensors and improve Deye dashboard ...

- Add template sensor 'Eksport do sieci' (W, positive when exporting to grid)
- Add template sensor 'Pobór z sieci' (W, positive when importing from grid)
  Both derived from sensor.inverter_deye_grid_power (negative=export, positive=import)

- Redesign deye_dashboard.yaml:
  - Add 'Energia teraz' card: PV, zużycie, eksport, pobór, bateria, tryb
  - Add 'Energia dziś' card: daily totals from Deye counters
  - Show programs 4 and 5 (previously missing)
  - Add history graph: PV + eksport + pobór

Fix heating dashboard: update entity IDs sterownik_1 → ibsystem after server migration ...

- Update all sterownik_1_rs0_id1_* entity refs in heating_dashboard.yaml
- Fix configuration.yaml: update template sensors and utility_meter to use new ibsystem entity IDs
- Remove stray set_heating_curve entry from utility_meter section
- Restore http: section header that was accidentally removed
- All heating dashboard entities now working (T1/T4/T5, moc, COP, energia)

Add G12W battery automation, IBSystem MQTT integration, HA configs ...

Zmiany:
- ha-configs/151/: Kopia konfiguracji HA TEST
  - automations.yaml: Automatyzacje G12W ładowania baterii
  - configuration.yaml: Główna konfiguracja z dashboardami
  - dashboards/: Deye, Ogrzewanie, IBSystem, ID35

- ibsystem/: Integracja IBSystem z MQTT
  - ibsystem2mqtt_v5.py: Bridge IBSystem → MQTT
  - config.yaml: Konfiguracja połączeń
  - ibsystem2mqtt_watchdog.sh: Health check i auto-restart

- docs/: Dokumentacja
  - G12W_BATTERY_AUTOMATION.md: Opis taryfy i automatyzacji
  - IBSYSTEM_MQTT_INTEGRATION.md: Opis integracji MQTT

Kluczowe naprawy:
- Program 6 Deye: zmiana z 21:00 Disabled na 22:00 Grid
- IBSystem: setting.light.X zamiast output.do.X dla sterowania
- Dashboard ID35: prawidłowe entity IDs (ibsystem_rs0_id35_*)
- Watchdog dla ibsystem2mqtt (cron co minutę)
