feat: add link to DFU mode manual page (#80)

* fix: hide unused menu bar on Linux and Windows builds
Menu bar is populated by default on Windows and Linux Electron builds even when not used.

This makes it so it is auto-hidden on dev builds (so it's still accessible if wanted), but fully disabled on "production" builds.

* feat: ensure user knows how to DFU mode flash
Fixes #52
