ux301: add env vars to enpass.desktop

[trwnh]

need to patch /usr/share/applications/enpass.desktop on line 10:

Before: Exec=/opt/enpass/Enpass %U
After: Exec=env QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCALE_FACTOR=1.5 /opt/enpass/Enpass %U

alternatively consider setting global env vars, assuming this scaling works best for all apps. (i wish per-app dpi was more common as in earlier versions of android... ugh)
