Pull request overview

This pull request refactors the Tuya integration's type information system by converting the module-level find_dpcode function into a class method on the TypeInformation base class. This is a code quality improvement that makes the architecture cleaner and more object-oriented.

Key Changes

• Moved find_dpcode from a module-level function to a class method on TypeInformation
• Introduced _DPTYPE as a ClassVar[DPType] on each TypeInformation subclass to identify the DPType
• Created explicit classes for previously generic type information: JsonTypeInformation, RawTypeInformation, and StringTypeInformation
• Updated all wrapper classes in models.py to reference type information classes instead of DPType enum values
