Merge develop and resolve conflicts

- Updated Json::Value to json::Value (lowercase namespace)
- Updated safe_cast to safeCast
- Updated constant naming (e.g., defaultAutoFillFeeMultiplier to kDefaultAutoFillFeeMultiplier)
- Merged testAugmentedFields with testFailHardValidation in Submit_test.cpp
- Updated namespace from xrpl to xrpl::test for test files
- Updated beast::unit_test::suite to beast::unit_test::Suite
