* **Documentation**
* Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples.
* Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns.
* **Refactor**
* Updated header include paths throughout the codebase to use lowercase naming conventions consistently.
* **New Features**
* Time and delay utilities added (ticks, ms, µs); SD card now uses an expansion-header CS pin; HTTP downloads warn when run on the GUI task and yield to avoid blocking.
* **Bug Fixes / Reliability**
* Many hard-crash paths converted to guarded checks to reduce abrupt termination and improve stability.
* **Tests**
* Unit tests added to validate time and delay accuracy.
* **Chores**
* License header and build/macro updates.
- Fix for `sdkconfig` generation: the keys that contained the MCU type in its name weren't properly upper-cased.
- Moved WiFi configuration property files to the user data path of the app instead of a fixed location.
- Moved more properties from `device.py` to `sdkconfig/default.properties`
- Fix for `device.cmake` device id parsing: separate basic property parsing from device id validation
- Created internal `tt::service::wifi::findServiceContext()`
- Changed Wi-Fi service id to lowercase (will change it for other services later)
