The inner `pub mod commands` block in network/mod.rs hosted three
unregistered Tauri commands (get_network_mounts_cmd,
check_mount_accessible, check_network_paths_batch) and was uncalled.
The non-command helpers in the parent module (get_network_mounts,
check_mount_accessibility, find_mount_for_path, parse_mount_info)
are also no longer referenced now that the commands are gone, but
they remain pub for potential future use without warnings.
- Remove the inner `pub mod commands { ... }` block.
- Drop the now-unused std::collections::HashMap import.
