fix(profiles): Switch Pro improvements

[ReenigneArcher]

Description

Route Linux Switch Pro controllers through descriptor-driven UHID, share the native handshake/reply protocol with Windows, and pack live IMU samples into Switch input reports. The API, control UI, tests, and docs now expose Switch Pro player LED output support and document the updated Linux backend behavior.
