feat(kpihistory): add KpiRollupHourly table + EF config + migration (plan #22 T1)

New KpiRollupHourly entity is the hourly pre-aggregated series backbone folded from raw KpiSample rows, letting long-range (30d/90d) trend reads scan ~60x fewer rows. Same (Source, Metric, Scope, ScopeKey) series key as KpiSample plus HourStartUtc bucket, folded Value, and MinValue/MaxValue/SampleCount fidelity columns. UNIQUE IX_KpiRollupHourly_Series (upsert key + range-read cover, with the default [ScopeKey] IS NOT NULL filter suppressed so Global rows participate) and IX_KpiRollupHourly_Hour for purge. Non-partitioned, [PRIMARY], no DB-role restriction. Claude-Session: https://claude.ai/code/session_01MtdgwpEeCUn6cUA5f1LMPj
