Fix: Hide system directories (.blobs, .trash, .dedup_temp) from all users

- Added directory name filtering in folder_fs_repository.rs
- Filters out directories starting with '.' in list_folders, list_folders_paginated, and count_directory_items
- Matches existing file listing behavior
- Also added Italian language to popular languages list

Fixes #87
