Run checkSyncSettings on lifecycle resume

[ArnyminerZ]

Purpose

Before #640 we were calling checkSyncSettings in the activity's onResume function.

However, after the PR, it was replaced by a simple LaunchedEffect. It should be LifecycleResumeEffect to match the original behavior.

Short description

Moved checkSyncSettings to a LifecycleResumeEffect.

Checklist

• The PR has a proper title, description and label.
• I have self-reviewed the PR.
• I have added documentation to complex functions and functions that can be used by other modules.
• I have added reasonable tests or consciously decided to not add tests.

Pull Request Overview

This PR changes when checkSyncSettings is called to match the original lifecycle behavior before PR #640. The change ensures that sync settings are checked whenever the screen resumes, not just when it's initially launched.

• Moved checkSyncSettings call from LaunchedEffect to LifecycleResumeEffect
• Added import for LifecycleResumeEffect
• Maintained the existing permission request logic in LaunchedEffect

That works. I wonder whether we can get rid of the effects at some point ...
