fix(lit): add requestUpdate to TextField, DateTimeInput, CheckBox

[ppazosp]

Description

Refactors TextField, DateTimeInput, and CheckBox (v0.8) to use the updateBoundData() helper introduced in #1022, ensuring these components call requestUpdate() after setData().

Without this fix, these components update the data model but do not trigger a re-render, so other components bound to the same data path will not reflect the new value.

Fixes #1023
Depends on #1022

Code Review

This pull request refactors data-binding logic across several UI components by introducing a centralized updateBoundData method in the Root base class, which reduces duplication and ensures consistent state updates. Feedback suggests further optimizing this by moving the path-existence guard clauses into the base method to simplify subclass implementations.

To further reduce code duplication, you could move the guard clauses from the subclasses into this helper method. This would make the updateBoundData method more robust and simplify the calling code in Checkbox, DateTimeInput, Slider, and TextField.

The signature could be changed to accept the object containing the path, rather than the path string itself.

For example:

protected updateBoundData(valueHolder: { path?: string } | null, value: DataValue) {
  if (!valueHolder || !('path' in valueHolder) || !valueHolder.path) {
    return;
  }

  if (!this.processor) {
    return;
  }

  this.processor.setData(
    this.component,
    valueHolder.path,
    value,
    this.surfaceId ?? A2uiMessageProcessor.DEFAULT_SURFACE_ID
  );
  this.requestUpdate();
}

Then, in the subclasses, the call would be simplified to this.updateBoundData(this.value, value); (or this.text) without any preceding guards.

  protected updateBoundData(valueHolder: { path?: string } | null, value: DataValue) {
    if (!valueHolder || !('path' in valueHolder) || !valueHolder.path) {
      return;
    }
    if (!this.processor) {
      return;
    }
    this.processor.setData(
      this.component,
      valueHolder.path,
      value,
      this.surfaceId ?? A2uiMessageProcessor.DEFAULT_SURFACE_ID
    );
    this.requestUpdate();
  }

Good suggestion. Since updateBoundData() is defined in PR #1022 (not this PR), I will keep this PR focused on the three component fixes and address the signature change in #1022 if the maintainers agree with the approach.
