Moves the database-independent logic of the SQL Server historian backend into a new shared library for the upcoming QuestDB backend (#666): status codes and bits, value/column mapping, StoredSample + quality clamp, the AtTime and aggregate evaluators, BucketPlan, LiveWritePreparer and HistoryUpdatePlanner (both with a resolutionTicks parameter, default 1), tag-name rules, the bootstrap failure cache, health counters, alarm event ids, the event continuation and severity clamp. The SQL Server backend now calls it; its T-SQL, TVP builders, connection, bootstrapper and catalog stay. Tests: StatusCodeOracleTests, ValueWriterPrepareTests, the column half of SampleRowMapperTests and ProcessedReadTests.Every_enum_member_is_either_served_or_refused move to the new Sql.Common.Tests under the same names. SqlServer integration tests get mechanical renames only. Test-name set across the three projects is identical to the baseline (160 tests).
