9b3b02e7 - Fix compressed-tensors loading for KV-cache-only quantized models (#47904)

Fix compressed-tensors loading for KV-cache-only quantized models (#47904) The early return `if not remaining_groups: return` skipped `apply_quantization_config` entirely when all config groups were handled by the FP8 kernel path (or when there were no weight quantization groups at all). This broke KV-cache-only quantized models because `apply_quantization_config` is also responsible for setting up KV-cache quantization observers and scales.
