0.1.2b1

Fix

Daily aggregation was broken

The groupby key used str(timestamp)[0:10] on EKZ timestamps like 20260407173000, which yields 2026040717 (hourly prefix) instead of the date 2026-04-07. This caused hourly instead of daily aggregation, producing ~24x more statistics entries. As a result, max_date never matched a day with the expected 96 slots, so last_import was never set correctly and no new data appeared in the HA Energy Dashboard.

After upgrading: clear the statistics for sensor.electricity_consumption_ekz_* and reload the integration to reimport all data correctly.
