[Angular 19] injectStore() runs before input signals are set.

Describe the bug

injectStore() runs before input signals are set which makes it throws an error at runtime if the form is provided as an input signal.

main.ts:8 ERROR RuntimeError: NG0950: Input is required but no value is available yet

Your minimal, reproducible example

Steps to reproduce

Open the shared link and see the error in the web dev tools.

The error is caused by the following code:

isValid = injectStore(
    this.form(),
    (state) => state.fieldMeta[this.name()].errors.length === 0
  );

In the component: FirstNameComponent

Expected behavior

The injectStore should call the business logic after input signals are set like Angular Query does.

Additional context

No response

Open the linked CodeSandbox and reproduce the error reported at main.ts:8, then inspect FirstNameComponent and the injectStore call using the form and name input signals. Done means the Angular example no longer throws NG0950 and injectStore runs its business logic after the input signals are set.
