ML-236 Exposure offset for equipment profiles (#238)

* Set `targetSdkVersion ` to 35

* unified zoom icons

* expose exposure and zoom ranges

* added list tile to set exposure offset for equipment profile

* added translations

* Update metering_screen.png

* use latest m3 packages

* fixed iap stub

* added missing field
