feat(console): add an "App" toggle to show/hide [app] log lines

The console mixed RPC traces, daemon output, and the wallet's own "[app] ..."
log lines with no way to hide the latter. Add an "App" checkbox alongside the
existing Daemon/Errors/RPC toggles. Since [app] lines share COLOR_INFO with
other info text, the filter matches them by their "[app] " prefix rather than by
color. Default on; unit test + i18n added.
