Summary

• Enable arboard's wayland-data-control feature so the system clipboard persists after the writing thread exits.
• Fixes invoice copy (key c) on Wayland compositors that implement wlr-data-control-unstable-v1 (Hyprland, Sway, etc.).

Problem

Under the default Wayland wl_data_device protocol, the clipboard "offer" is dropped when the owning client goes away. handle_clipboard_copy in src/ui/key_handler/mod.rs spawns a short-lived thread that calls arboard::Clipboard::set_text and exits immediately, so the offer disappears before the user can paste. The log shows Invoice copied to clipboard (the call returned Ok), but the clipboard is empty.

Fix

Activate arboard's wayland-data-control feature, which uses wlr-data-control-unstable-v1. This protocol stores the clipboard contents in the compositor, so the data survives the writing thread terminating. No code changes required — only a feature flag in Cargo.toml.

Test plan

• cargo build succeeds.
• Take an order on a Wayland session (Hyprland), press c on the invoice popup, paste into another window — invoice text is present.
• Verify X11 sessions still work (arboard falls back to the X11 backend when not on Wayland).
