🔧 chore(UpdateRequest.py): change field_type from "code" to "NestedDict" to improve clarity and semantics

🔧 chore(base.py): handle "dict" and "NestedDict" types in params parsing to ensure correct conversion from frontend data
🔧 chore(llms.py): change field_type from "code" to "dict" for model_kwargs field to improve semantics
🔧 chore(utilities.py): remove field_type "code" for fields with dict values to improve consistency
🔧 chore(constants.py): add "dict" and "NestedDict" to DIRECT_TYPES list to reflect available field types
🔧 chore(util.py): remove replace_dict_type_with_code function as it is no longer needed
