* fix(zeta): add camera extraComponent to Home Assistant

HA 2026.2 introduced an ai_task component that's unconditionally
imported during WebSocket service description loading. The import
chain (ai_task → camera → img_util) requires pyturbojpeg, which
wasn't present. Adding camera as an extraComponent pulls in the
required Python dependencies via the NixOS HA module.

* feat(zeta): add mobile_app component to Home Assistant

Enables iOS companion app access.

* fix(zeta): explicitly enable mobile_app in HA configuration

extraComponents only makes packages available; the component also needs
to be declared in configuration.yaml to be loaded by HA.
