Restore trash import for move_vault_to_trash functionality

The trash crate is needed for the move_vault_to_trash function which
moves vault files to the system trash instead of permanently deleting
them. Clippy incorrectly marked it as unused because it's only used
within a cfg(not(target_os = "android")) block.
