Tauri let the user rename how QBZ announces itself to Qobuz Connect;
the Slint port lost the UI entirely while keeping the persistence and
the announce path (same device_name key in qconnect_settings.db, read
by connect() -> bootstrap_remote_presence). Restored 1:1: a text row
in Settings > Playback next to the QConnect startup select (LineEdit
mirroring the ListenBrainz token row, placeholder = the resolved
default 'Qbz - {hostname}'), a new settings-string callback channel
through the settings chain, and a live-service setter so a rename
takes effect on the next connection without an app restart — exactly
Tauri's semantics (no live re-announce; the row description says so).
Trim-only validation like Tauri; empty clears the override. Two new
msgids across the 8 locales.
