Extend the session timeout in TrueNAS Scale

This is something that other people have come up with workarounds for already.

As explained in this Github comment¹, and raised in This Issue² on IXsystems’ Jira instance…
…Which has been superceded by this ticket³.
…and subsequently turned into an improved one-liner, and documented on Tom Schlicks Blog⁴
…
BUT STILL NOT FIXED…

I figured I’d save the one-liners Tom made here for posterity

TrueNAS Scale sed one-liner_{Lang: shell}

sed -i 's/auth.generate_token",\[300/auth.generate_token",\[129600/g'  /usr/share/truenas/webui/*.js

TrueNAS CORE sed one-liner_{Lang: shell}

sed -ie 's/auth.generate_token",\[300/auth.generate_token",\[129600/g' /usr/local/www/webui/*.js

Thanks to TOM SCHLICK for making this easy for me!!
