Pull request overview

This PR updates the move-to-folder snackbar messaging to use dedicated “moved to Spam” strings (including plural forms) when the destination folder is Spam.

Changes:

• Add new snackbarMessageMovedToSpam and snackbarThreadMovedToSpam string resources across multiple locales.
• Update MainViewModel.showMoveSnackbar() to switch snackbar text based on whether the destination folder role is SPAM.
• Refactor snackbar title construction into helper methods for threads vs. single message moves.
