Rename icons, fix T-Lora Pager config and more (#502)

* **New Features**
  * Added NFC chip-select to SD card hardware configuration.

  * Renamed LVGL lock API (timed → lvgl_try_lock) and updated callers.

* **Documentation**
  * Updated module README and license files; added Apache-2.0 license document.
