This commit introduces a folder browsing button in the Dashboard GUI, allowing users to select a folder for photo scanning. It also implements path normalization and validation using new utility functions from the path_utils module, ensuring that folder paths are absolute and accessible before scanning. Additionally, the PhotoManager class has been updated to utilize these path utilities, enhancing the robustness of folder scanning operations. This improves user experience by preventing errors related to invalid paths and streamlining folder management across the application.
