enhancement (dashboard, wiki): improve logging for obvious errors, wiki improvements

Some errors from firewall (like os error 32) are really not obvious for users, they should be captured and logged correctly
Also sometimes handshake errors on wired could mean their cable is not working properly, or port is malfunctioning/not compatible with adb

There are more errors, like os error 11 (also could be related to firewall), 10013, 10054, 997 (Overlapped I/O operation is in progress)

On top of this, check for encoders upon launching steamvr on linux should include note on nvidia to relogin/reboot

~~On wiki, many people seem to get confused how to combine environment variables with vrmonitor fix, this should be fixed by including all possible combinations (hybrid gpu + sway + vrmonitor, mint paths, etc) (maybe even merging most of them if they can't affect already working setup)~~
~~Also on wiki, vrmonitor fix should be declared mandatory (and not optional), so people won't miss it~~
(implemented)
