Introduce LedType/LedMap and refactor pixel types
Rename pixel::Type/Map to pixel::LedType/pixel::LedMap and centralize type metadata into a constexpr TypeInfo table in pixeltype.h. Add helper APIs (GetTypeName, GetMapName, GetTypeInfo, GetTxH) and replace many callsites accordingly; remove the old pixeltype.cpp implementation. Update PixelConfiguration to use the new info (led count, protocol, default/max SPI Hz, map), simplify validation, and compute refresh/clock settings from TypeInfo. Make utils::ToValue/FromValue constexpr with static_asserts. Propagate enum and API name changes across gd32_rdm_responder, lib-pixel, lib-pixeldmx and JSON/status code. Minor formatting, include fixes, and copyright year updates (2026).
