Live-save bar settings as you edit

Every layout mutation (add/remove/reorder, settings dialog Apply,
position or centerAnchor change) now writes ~/.config/omarchy/bar.json
immediately. No more Save button — replaced with an inline 'Auto-saving
to ...' status line next to Reset to defaults.

To stop the FileView feedback loop (write → inotify → reload → set
draft → write again) the shell keeps a one-shot suppressReload flag
that swallows the userFile.onLoaded triggered by our own setText.
