fix: Show outdated browser warning immediately

[Gudahtt]

Description

The outdated browser warning logic has been updated to ensure that it gets shown immediately for new installations if applicable.

We have a timer setup to ensure we don't bother users too often with this warning; it recurs every two days. However, it was initialized to the current date, so new users would not see it for two days.
