* windows: Support alt install paths
Advanced users are leveraging innosetup's /DIR switch to target
an alternate location, but we get confused by things not existing in the LocalAppData dir.
This also hardens the server path lookup code for a future attempt to unify with a ./bin prefix
* Fit and finish improvements for windows app
Document alternate install location instructions for binaries and model.
Pop up progress UI for upgrades (automatic, with cancel button).
Expose non-default port in menu to disambiguate mutiple instances.
Set minimum Windows version to 10 22H2
This moves all the env var reading into one central module
and logs the loaded config once at startup which should
help in troubleshooting user server logs
