Integrate mjgodat's keyboard/display Companion, USB Companion, Repeater and Room Server support for Cardputer-Adv with Cap LoRa-1262. Fix UI retry dispatch and ACK ownership, packet/storage bounds, numeric input validation, sparse channel selection, optional-display shutdown, keyboard layout limits, reserved GPIOs and Windows cross-drive includes. Retain all 350 contacts and queue capacity using the existing contact cache; account for the custom UI's runtime allocations in the RAM admission gate. Carry the MultiMote and DejaVu notices with firmware packages and add CI coverage for all four board roles plus the shared T-Deck Companion. Validation: all four Cardputer roles and the T-Deck BLE Companion build; Cardputer sanitizer, UI, layout, ownership, licensing and storage tests; 65 RAM-policy tests and 14 contact-cache tests. PlatformIO ran serially. PR: https://github.com/mikecarper/MeshCore/pull/26
