2026.7.8-beta.2

Fixed

• Multi-entity: combining entities from different state_class families (measurement vs total/total_increasing) silently rendered zeros or NaN. The card now shows an error message and the visual editor warns on incompatible pairings.
• Editor: switching to daily mode while a secondary entity was configured produced an unrecoverable error card. The switch now clears the multi-entity options (combination is hourly-only).
