MS-1188 Short-term logout fix

[luhmirin-s]

JIRA ticket
Will be released in: 2025.3.0

Root cause analysis (for bugfixes only)

First known affected version: 2025.3.0

• Compounded issue that leads to some racing:
  • In both cases, the logout use case is called in the view model-scoped coroutine. Navigation happens right after the start of the logout coroutine, which kills the VM scope and cancels the logout navigation (sometimes, this is the racing part).
  • Navigation to the root leads to checking for "logged in" state (which succeeds if navigation happened faster than the data cleanup) and opens the dashboard instead of the "login request" placeholder.

Notable changes

• Made logout use case blocking (while still executing on the IO dispatcher) to block navigation until the data cleanup is done.
• Minor cleanup of the navigation graph actions to make it consistent.

Testing guidance

• Login, do biometric flow (so that event upload is forced), attempt to log out. Repeat multiple times.
• Should navigate to the login request screen every time.

Additional work checklist

• Effect on other features and security has been considered
• Design document marked as "In development" (if applicable)
• External (Gitbook) and internal (Confluence) Documentation is up to date (or ticket created)
• Test cases in Testiny are up to date (or ticket created)
• Other teams notified about the changes (if applicable)
