Ports the M5Stack Cardputer Advanced variant originally created by Stachugit (https://github.com/Stachugit/MeshCore-Cardputer-ADV) to the v1.15.0 codebase, making it buildable against the current upstream. All Cardputer-specific code (hardware variant, keyboard UI, display driver) is the work of Stachugit. This PR contributes it upstream so future releases include official Cardputer support without manual porting. New files (originally by Stachugit): - boards/m5stack_cardputer.json - variants/m5stack_cardputer/ - src/helpers/ui/M5CardputerDisplay.{h,cpp} - examples/companion_radio/ui-keyboard/ - examples/companion_radio/UITask.h v1.15.0 API compatibility changes: - NodePrefs: add screen_timeout_seconds - MyMesh: expose saveContacts(), saveChannels(), factoryReset() as public - MyMesh: add queueOutgoingMessageForBLE() Build target: env:M5stack_cardputer_cap_lora1262_companion RAM: 49.9% | Flash: 42.2% of 8MB partition Co-Authored-By: Stachugit <https://github.com/Stachugit> Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
This PR ports the M5Stack Cardputer Advanced + Cap LoRa-1262 variant originally created by @Stachugit (repo) to the v1.15.0 codebase.
All Cardputer-specific code — hardware variant, keyboard-driven UI, and LVGL display driver — is the work of Stachugit. This PR contributes it upstream so future MeshCore releases include official Cardputer ADV support without manual porting.
