Check offline updates for incompatibility

[samfreund]

Description

We've been experiencing a variety of issues where people are performing an offline update with an incompatible jar, which leads to bricking their device. This PR aims to help users avoid this issue. We will deny offline updates built for a different platform, as well asking for confirmation when updating with a dev jar, or a jar built for a different year than the current image.

Note that this functionality is entirely dependent on the filename of the jar, and does not use any metadata.

This PR additionally increases the snackbar message timeout from 2 to 5 seconds, as we've found 2 seconds isn't sufficient to fully read the message.

closes #2357
