Pull Request Overview

This PR updates naming throughout the codebase to replace "ERC1538" references with "Diamond proxy" terminology, reflecting a migration from ERC1538 proxy pattern to Diamond proxy pattern. This appears to be part 1 of a larger refactoring effort.

• Replace all occurrences of "ERC1538" with "Diamond" or "DiamondProxy" in variable names, comments, and configuration
• Update deployment and configuration scripts to use new Diamond proxy naming
• Maintain backward compatibility by keeping deprecated ERC1538Proxy config field

• [nitpick] The variable name 'diamondQueryInstance' suggests it should be a Diamond-related type, but it's still using 'ERC1538Query'. Consider updating the type name to match the Diamond pattern or using a more generic name like 'queryInstance'.
