v1.11.0: CCS811 en daemon + fix filtrage + I2C 10kHz requis

Vérif terrain sur pro100 : à 100 kHz le CCS811 renvoie des valeurs corrompues
0x8000 (32768) par clock-stretching, et le modèle oneshot-reset-toutes-les-10s
ne donne que le 1er échantillon post-init (garbage). Refonte :

- CCS811/daemon.py: service long-running (Type=simple, Restart=always). Init 1x,
  boucle lecture/écriture 10s, filtre eCO2 dans [400,8192], re-init auto sur
  erreurs I2C répétées. Remplace write_data.py (supprimé).
- CCS811/get_data.py: lit la dernière ligne data_CCS811 au lieu du capteur
  (évite la collision I2C avec le daemon -> corruption observée).
- setup_services.sh: service daemon + self-heal suppression de l'ancien .timer;
  activation hors boucle timers.
- launcher.php: .timer -> .service (map statut + allowedServices x2).
- update_firmware.sh: redémarre le daemon à l'OTA.
- doc: README (archi daemon + I2C 10kHz confirmé requis), CLAUDE.md, changelog.
