Summary

Add type-aware aggregate series to Home Assistant entity history: measurement summaries, consumption, state activity, and typed event counts. Preserve existing source/analysis behavior and provide calendar periods, cumulative baselines, and coverage indicators.

HA history + statistics
  -> typed aggregation calculations
  -> independent derived series
  -> interval bars / cumulative lines

Closes #67.

Evidence

• Before: Existing panel/domain baseline tests and type checking pass; typed events and consumption series are unavailable.
• After: Implementation and verification in progress. This draft tracks integration of calculation, controls/persistence, and chart/data-loading work.

Merge Danger

Door: two-way

Existing configurations remain valid; aggregate definitions are additive and do not write recorder history.

Blast Radius: history

Changes affect history controls, data ingestion, calendar aggregation, and chart rendering. Persistent counter entities and analysis composition are deferred.
