Removes the remaining production unwraps in the UI (fit view, save, macOS
shortcut labels, layers rows, swatch rows) and the CLI perf budget runner
(errors are reported instead of expect), and adds the deny attribute to
ui-egui, the desktop app and the web app.
vectorcraft-cli's main.rs is left without the attribute because an open
PR (#13) edits that file.
