Fix flaky tests on the ci

This is just an issue to remind us and to get other people to look into this.

Currently tests are flaky on the ci (they mostly fail):

• is it because of the interaction of tui / cargo insta ? (ratatui test suite seems to be passing)
• is it because of the nature of banwhich maybe network values are different (unlikely)

If we could pinpoint the most flaky tests and disable those I think that would be a good starting point. We can always re-enable stuff gradually after.
