MS-122 Secure prefs everywhere

[luhmirin-s]

JIRA ticket
Will be released in: 2025.3.0

Notable changes

• Moving a couple of remaining cases of shared prefs usage to the encrypted counterpart to avoid accidentally leaking some IDs/domain. The risk was always very low, but this ticket has been in the backlog for too long by now.
• Did not move the language helper since it is fine as-is (it stores only the language code), and the performance penalty from encryption might affect app startup times.

Testing guidance

• Use the app as usual - upsync progress should be reported correctly.

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)
