Happy Hare now writes mmu lane data to the moonraker db similar to AFC, so we can normalize to the one implementation. For now, i've just re-ordered it so that the moonraker db is checked first. I want this because I've actually updated the happy hare data to include more data than we had access to via the "mmu" object. For happy hare we now have access to vendor name, which we can eventually use to further fine tune the auto-matched filament preset.
* feat(webview): enable context menu
This enables the ability (at least on MacOS) to reload the webview.
* fix(webview): add handler for webview error
Adding this un-covered the following error when trying to load a the printer page using http and hostname:
```
OnError: error loading page about:blank wxWEBVIEW_NAV_ERR_OTHER The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.
```
* fix(macos): disable App Transport Security policy
Disables the [App Transport Security](https://developer.apple.com/documentation/bundleresources/information_property_list/nsapptransportsecurity) policy that blocks loading http urls (via hostname...ip addresses were fine because ip addresses can't have certs, so they would be excluded from the ATS restriction).
