unPhone implementation and more (#169)

- Implemented [unPhone](https://unphone.net/) v9 board
- Updated `.clang-format` to better reflect the intended code style
- Fix SD card compatibility issues for all boards (frequency wasn't set well)
- Moved `I2cDevice` class from CoreS3 board project to TactilityHeadless project
- Tactility configuration now has default empty lists for apps and services fields
- Fix for Launcher app: we don't need padding when showing it vertically
- Fix for I2cDevice read/write calls that checked for `esp_err_t` instead of `bool`
- Fix for TinyUSB init that checked for `esp_err_t` instead of `bool`
