feat: Add a menu item to reload the configuration files

Add a "Reload Configurations" item to the status-bar menu so users can
manually re-sync every stored configuration's remote formatter files
instead of waiting for the launch / hourly-timer downloads.

- ApplicationDelegate: reloadConfigurations(_:) calls download() on each
stored configuration, reusing the existing launch/timer download path,
which re-fetches over HTTPS and overwrites the shared cache. Fire-and-
forget: download() self-coalesces while a download is already running.
- MainMenu.xib: insert the item plus a trailing separator after the
configuration list, in its own group above "Manage Configurations...".
