fix: clipboard content lost on Linux after copy

ClipboardContext was created locally and dropped immediately, causing
the app to lose X11/Wayland selection ownership before any paste.

Move the context into RootComponent as a persistent field for the
app's lifetime. Route RecordsComponent's direct clipboard call
through Action::CopyToClipboard so all copy paths go via one place.
