[DO NOT SQUASH] Backport Breadcrumbs component to 25.2#9536
Merged
Conversation
…9380) Implements `BreadcrumbsItem`: the seven constructors mirroring `SideNavItem`'s overload set, the `path` accessors (`getPath()`, `setPath(String)`, `setPath(Class<? extends Component>)`, `setPath(Class, RouteParameters)` — the class overloads resolve via `RouteConfiguration` exactly like `SideNavItem`), and the inherited `HasText` / `HasEnabled` / `HasPrefix` surface. Stacked on #9379 (scaffolding) — base branch is `breadcrumbs-flow-scaffolding`, so review/merge that first. Kept as a draft until the base PR lands and this can retarget `main`.

…9531) Flow moved page-title resolution from the internal `RouteUtil` to the public `Router.resolvePageTitle` (vaadin/flow#24647), removing the `RouteUtil.resolvePageTitle(Instantiator, ...)` overload that `Breadcrumbs` relied on. This broke `vaadin-breadcrumbs-flow` compilation on `main`: ``` Breadcrumbs.java:[436,17] cannot find symbol symbol: method resolvePageTitle(Instantiator,Class<? extends Component>,RouteParameters,QueryParameters) ``` `Mode.ROUTER` item titles are now resolved through the public `Router.resolvePageTitle(target, routeParameters, queryParameters)`, obtained via `ComponentUtil.getRouter(this)`. This drops the manual `VaadinService.getCurrent().getInstantiator()` lookup, since the new API resolves the instantiator itself. The unit test's mocked `Router` is replaced with a spy over a real `Router`, so the real `resolvePageTitle` runs (titles are asserted) while `getRegistry()` stays stubbed to return the application registry directly.

`BreadcrumbsItem.setText` used the default `HasText#setText`, which
replaces all of the item's content — so calling it after
`setPrefixComponent` removed the prefix (e.g. an icon).
```java
BreadcrumbsItem item = new BreadcrumbsItem("Inbox (2 items)");
item.setPrefixComponent(new Icon(VaadinIcon.ENVELOPE));
item.setText("Inbox (3 items)"); // icon was lost
```
The text is now held in a dedicated text node managed through
`SignalPropertySupport`, the same approach `Button` and `Badge` use.
`setText`/`bindText` only update that text node, so the prefix (and any
other slotted content) is preserved.
Fixes #9533
