Replace Tuya remap methods with helper class

[epenet]

Proposed change

The current remap methods are confusing:

• the target range (0-100 in cover, 1-100 in fan, 0-360 / 0-100 / 0-255 / MIN_MIREDS-MAX_MIREDS in light) were passed in both remap_value_from and remap_value_to
• the light platform was creating fake IntegerTypeInformation classes in order to access the helper method there

This replaces the current methods with a helper class so that:

• the source/target range is always declared explicitly (no more defaulting to 0-255)
• the reverse option is a kw-only argument
• fake IntegerTypeInformation instances are replaced with RemapHelper instances

Pull request overview

This PR refactors the Tuya integration's value remapping functionality by introducing a new RemapHelper class to replace the previous confusing methods. The changes improve code clarity by making source and target ranges explicit, converting reverse to a keyword-only argument, and eliminating fake IntegerTypeInformation instances that were previously created just to access helper methods.

Key changes:

• Introduced RemapHelper dataclass with explicit source/target ranges and factory methods
• Replaced IntegerTypeInformation.remap_value_to/from methods with RemapHelper instances
• Made type_data field non-optional in TypeInformation class since it's always provided
