Merge develop into main (#318)

- Disable `DisplayDriver` for `St7701Display` (on CYD 4848)
- Improve `GraphicsDemo`: check for feature capability and show alert dialog if there's an issue
- `DevelopmentService` installs to `/data` instead of `/sdcard`
- Fixed `tt_app_get_data_directory()` and `tt_app_get_data_directory_lvgl()` (C++ to C)
- `tt_kernel.h` now defines `MAX_TICKS`
- `tt_init.cpp` now exports `esp_log()` which is required since ESP-IDF 5.5
