feat(preferences): ✨ Add email sync interval setting (#710)

* feat(preferences): ✨ Add email sync interval setting

Introduced a new property `EmailSyncIntervalMinutes` in the `IPreferencesService` interface to allow users to configure the email synchronization interval in minutes. This feature enhances user control over email sync behavior.

• Updated `resources.json` to include translations for the new setting.
• Implemented the logic for the new property in `PreferencesService.cs`, with a default value of 3 minutes.
• Added binding and UI support in `AppPreferencesPageViewModel.cs` and `AppPreferencesPage.xaml` to allow users to modify the sync interval.
• Integrated the new setting into `ServerContext.cs` to dynamically adjust the synchronization timer based on user preferences.

This change improves the user experience by providing customizable email synchronization settings.

* Minimum interval and added an icon.

* Proper SetProperty usage.

* Making sure the minimum sync interval is 1 in the ServerContext.

* Making sure the minimum is applied to first trigger of the sync timer.
