Rerun catches SIGINT and treats it as a crash when serving the web viewer

[teh-cmc]

Which of course implies a crash report sent to posthog and everything.

$ rerun --web-viewer examples/out/api_demo_a1.rrd

I think this is the same as #1367 (and #1312? I'm confused about these)? If yes, close this old one, this here is more expressive

[teh-cmc]

I don't think these are the same thing? These previous tickets were about the fact that it's impossible to kill the web-server... but clearly now we can (so this got fixed at some point..?!), but now this gets caught as a crash :|

I'll go ahead and add this ticket to the current cycle, this seems like one of these uber annoying subject matter that could benefit from all of us being in the same room.
