Remove the offline check from metering startup

[tescalada]

Metering-provider startup no longer checks the offline setting. Offline mode keeps the ground from contacting the cloud and has nothing to do with metering, but ensure_metering_runtime and metering_lifespan both skipped startup when it was on, so a ground running offline never started its meter driver.

Both checks are removed, along with ConfigDict.is_offline() and the tests that asserted the skip. With no driver registered, startup still skips through the existing "metering provider is not configured" path.
