Certificate display switches to expired-view (if expired) after opening the certificate view (EXPOSUREAPP-8837)

[BMItr]

This PR addresses Exposureapp-8337.
"Certificate display switches to "expired-view" only after app re-start"

About:
The check whether a certificate has expired or not usually runs every 24hours.
This PR adds a second check which is triggered opening the certificate-overview.

How-to-test:

• scan a Certificate which will expire in some minutes (can be found in the QR-Example Folder "Special QRs" or CLI Tool-> vc gen --exp 1minute)
• opening the CertView (MainScreen->BottomBar) will show a list of your certificates.
• if the certificate is expired it should show up already in the certificate overview screen

@BMItr Is it acceptable that we do multiple validity checks now while the App in foreground ? can you please align with Max?

do not merge yet.
I found an underlaying issue regarding Certificate Checks in general. (under investigation)
update:
The state check happens inside the respective flow of the repos. But the flows are shared flows and they cache the data as long as they have subscribers. This explains the flaky behaviour, why it was sometimes working and sometimes not. I fixed this by adding non cached (aka fresh) flows. State check should now work as expected.
