Harden nRF52 OTA, USB sessions, and T096 controls

Bind Companion replies to request transports, make dual-CDC USB sessions nonblocking and reconnect-safe, and harden nRF52 watchdog/OTA storage paths. Fix T096 button debounce, display wake, sleep races, and the compact message layout; add exact WisBlock OTA profiles plus expanded native/static/HIL documentation.
