Cardputer adv and more (#395)

- Fixed TCA8418 driver
- Updated T-Lora Pager for TCA driver fixes
- Fixed issues with T-Lora keyboard driver
- Implemented Cardputer Adv
- Cleanup of Cardputer (regular)
- Fix sdkconfig for E32R28T and E32R32P
- Disable Wi-Fi on boot (was accidentally pushed before)

 ## Higher Priority
 
+- Fix Cardputer (original): use LV_KEY_NEXT and _PREV in keyboard mapping instead of encoder driver hack (and check GPIO app if it then hangs too)
 - Logging with a function that uses std::format
 - Calculator bugs (see GitHub issue)
 - Expose http::download() and main dispatcher to TactiltyC.
