Triplex should be able to be start when internet is unavailable

[ryumy97]

To replicate: Open VS code without any internet access or network firewall that makes statsig call fail.

What happens: fetch statsig fails and rendering gets stuck in the triplex logo. What is expected: App should continue to be working while the error log around statsig should be shown

So there's two things needed here:

1. Fix statsig throwing exceptions so it can start without internet (or it being blocked)
2. Fix supabase throwing exceptions so it can start without internet

Happy for anyone to take a look at this 🙏 it'll need some debugging time to figure out what's going on
