chore: bump frontend version to 1.0.107

Fixed the download selected button not displaying count properly.
The translation key 'gallery.downloadSelected' was not receiving
the count parameter for interpolation, causing "{{count}}" to
display literally instead of the actual number.

Fixes the issue where the button showed:
- "Download {{count}} Selected" instead of "Download 2 Selected"
- "{{count}} ausgewählte herunterladen" instead of "3 ausgewählte herunterladen"
