Configuration-002: sp_PublishGeneration is transaction-nesting aware
(BEGIN TRANSACTION vs SAVE TRANSACTION on @@TRANCOUNT) so a caller's outer
transaction survives a publish failure; sp_ValidateDraft wrapped in TRY/CATCH.
Configuration-003: ValidatePathLength uses the cluster's actual Enterprise/Site
lengths when available, falling back to the conservative approximation.
Configuration-006: ResilientConfigReader treats a command-timeout
TaskCanceledException as a fault (not caller cancellation) and falls back.
Configuration-009: removed the checked-in plaintext sa connection string;
CreateDbContext now requires OTOPCUA_CONFIG_CONNECTION.
