feat: add location search to location picker

issue no. :#82 (closed) Description

This MR introduces a location search feature to the map picker, improving usability and efficiency.

Previously, users had to manually navigate the map to select a location, which could be slow and imprecise. With this update, users can now search by place name or address and quickly select accurate locations.

Note: These changes were initially committed to the develop branch by mistake and have been safely moved to the feature/location-search branch. The develop branch has been restored to a clean state.
