Investigate migration to new control-flow templating

[hudson-newey]

Angular 17 introduced new control flow templating

@if (condition) {
	<p>conditionally render be {{ condition }}</p>
}

The new templating is marginally faster than the old directive-based control flow and migration means that we don't have two different control flow styles in our templates

We should consider running the Angular migration script

$ ng g @angular/core:control-flow
