Unable to attach or view photos in Windows app

[raherin]

Photos do not appear to be working in the Windows implementation of the app. To reproduce the issue:

1. Use the QGIS plugin to create a new basic project and synchronise it to the server

2. On your pc/laptop, move a photo to the project directory

3. In QGIS, set the survey layer to 'editable' and add a new point

4. Attach the photo in the project directory using the attachment widget in the survey form

5. Save and sync changes in the plugin

6. Open the windows version of the Mergin Maps app

7. Download the project and open it

8. Click on the point you created, the photo will not be visible, the terminal will show the following error message: qrc:/com.merginmaps/imports/MMInput/editor/inputexternalresource.qml:120:5: QML QQuickImage*: Cannot open: file://c/Users/raahe/AppData/Roaming/Lutra Consulting/Input/INPUT/projects/mm_windows_photo_test/IMG_20231127_084655.jpg

9. In the Windows app, create a new point and attach a photo, the app will give the following error: "2024-04-05T13:00:51.940Z Select image: Failed to copy image file to C:/Users/raahe/AppData/Roaming/Lutra Consulting/Input/INPUT/projects/mm_windows_photo_test/IMG_20231127_101343.jpg\n" qrc:/com.merginmaps/imports/MMInput/editor/inputexternalresource.qml:120:5: QML QQuickImage*: Cannot open: file://c/Users/raahe/AppData/Roaming/Lutra Consulting/Input/INPUT/projects/mm_windows_photo_test//IMG_20231127_101343.jpg
