Description

This PR upgrades the @formio/angular library to work with Angular 19. The biggest change was that the "standalone" flag now defaults to "true" so for all the components, we need to provide that flag and set it to false.

Breaking Changes / Backwards Compatibility

None.

It looks like an angular dependency (glob) doesn't support node < 20, although angular claims that 18 is actively supported. Is this going to be an issue for developer customers? I can easily upgrade the CI runner to 20, but I just wanted to check if there's something we need to be doing differently here.
