feat(configdb): add AuditLog migration with monthly partitioning and DB roles (#23)
Bundle C of the #23 M1 foundation. Creates the centralized AuditLog table with the partition function, partition scheme, partition-aligned non-clustered indexes, and the two access-control roles documented in alog.md §4. Schema: - pf_AuditLog_Month: RANGE RIGHT, 24 monthly boundaries (Jan 2026 – Dec 2027). - ps_AuditLog_Month: ALL TO ([PRIMARY]) — dev/test parity. - dbo.AuditLog: created via raw SQL ON ps_AuditLog_Month(OccurredAtUtc). Composite clustered PK {EventId, OccurredAtUtc} (partition column must be part of the clustered key). 22 columns matching the EF AuditEvent model. - 5 reconciliation/query non-clustered indexes from alog.md §4 (Channel_Status_Occurred, CorrelationId filtered, OccurredAtUtc, Site_Occurred, Target_Occurred filtered) — all partition-aligned. - UX_AuditLog_EventId: non-aligned UNIQUE on EventId alone (preserves InsertIfNotExistsAsync idempotency from M1-T8). Non-aligned because partition-aligned unique indexes require the partition column in the key, which would weaken to composite uniqueness; the purge story (M2/M3) rebuilds this index around partition switches. Access control: - scadalink_audit_writer: GRANT INSERT + GRANT SELECT, DENY UPDATE + DENY DELETE on AuditLog. The explicit DENY guarantees later db_datawriter membership cannot quietly re-enable mutation. - scadalink_audit_purger: GRANT SELECT on AuditLog, GRANT ALTER on SCHEMA::dbo (enables ALTER PARTITION FUNCTION SWITCH and SWITCH PARTITION). Both role definitions are idempotent (IF DATABASE_PRINCIPAL_ID IS NULL). Down() drops in reverse dependency order with IF EXISTS guards. Integration tests (tests/ScadaLink.ConfigurationDatabase.Tests/Migrations/): - MsSqlMigrationFixture: connects to the running infra/mssql container (or the SCADALINK_MSSQL_TEST_CONN override), creates a unique per-fixture database, applies the migrations, drops the DB on dispose. Marks itself Available=false when MSSQL is unreachable so tests early-return cleanly on CI without the dev container. - AddAuditLogTableMigrationTests: 8 tests covering table existence, partition function/scheme, partition-aligned PK, the 5 named indexes, both roles' grants, and a smoke test that a writer-role user receives SqlException with "permission" on UPDATE AuditLog. ConfigurationDatabase tests: 142 passing -> 150 passing (8 new integration tests). Full solution builds clean. Package: tests project locally overrides Microsoft.Data.SqlClient to 6.1.1 (EF SqlServer 10.0.7 needs >= 6.1.1; central package version is pinned at 6.0.2 for the production ExternalSystemGateway).
