- Created `tactility-headless` to support ESP32 firmwares that don't require graphics
- `tactility` subproject now contains both PC and ESP32 code (to avoid having to split up `tactility` and `tactility-headless` into separate projects, which would result in a very complex dependency tree)
- `tactility` subproject is now defined as component for ESP32 and as regular module for PC
- Improvements for dispatcher
- Added `project-structure.puml` to docs
- `Gui` service now depends on `Loader` service instead of the reverse
- Added `statusbar_updater` service for updating Wi-Fi and SD card icons
### General
- Added support for SD cards in `HadwareConfig`
- Properly disabled PC build for now (I was still getting error emails)
- Updated `README.md` with a device compatibility table
### T-Deck:
- Implemented SD card support
- Logging message cleanup
- Updated `config,h` with various new settings
- Reduced stack depth from `8096` to `5000`
