refactor(#655): delete the dead driver-side history capability
HistoryRead is served server-side by IHistorianDataSource; nothing ever dispatched to a driver's IHistoryProvider. Removes IHistoryProvider, the OpcUaClient history passthrough, DriverCapability.HistoryRead (+ resilience tier rows and AdminUI row), HistoryReadStatusException and its node-manager catches, and the tests that only covered them. Shared result types and HistoryAggregateNotSupportedException stay (moved to Historian/HistoryReadContracts.cs). A stored ResilienceConfig still carrying a HistoryRead key parses (diagnostic only; new test). Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
