Case-Insensitive Hostname Matching for Batch and Benchmark Definitions

Hostname matching used in batch and site definitions is currently case sensitive, so devices whose hostname casing differs from the defined criteria can be excluded even when a definition is intended to cover all devices. This causes benchmark queries scoped to 'All Devices' to omit devices unexpectedly, without any indication to the administrator that a case mismatch is the cause. This enhancement would make hostname matching case-insensitive across batch and site definitions used in Benchmark and related queries. Customers would gain more reliable and predictable device coverage in their benchmark and discovery operations without needing to manually verify hostname casing.
