v1.10.0: intégration capteur CCS811 (TVOC/eCO2, I2C)

Nouveau capteur de qualité d'air CCS811 sur le bus I2C, calqué sur le
pattern S88 (local-only, pas encore dans le payload de transmission).

- CCS811/get_data.py (lecture live) + write_data.py (timer 10s, self-heal table)
- table data_CCS811 (timestamp, eCO2, TVOC) dans create_db.py
- config CCS811 (bool) + CCS811_address (0x5A/0x5B, défaut 0x5A) dans set_config.py
- service+timer systemd nebuleair-ccs811-data (10s) + ajout boucle d'activation
- admin.html: case d'activation + dropdown adresse I2C
- sensors.html: carte Get Data (TVOC + eCO2)
- database.html + launcher.php: consultation/export/stats data_CCS811
- lib adafruit-circuitpython-ccs811 dans installation_part1.sh
- CCS811/README.md: câblage, adresses, warning clock-stretching I2C sur Pi
- CLAUDE.md + changelog mis à jour
