Declare the new frontend test dependencies, avoid the finalize options shadowing lint error, and add explicit assertions in frontend-test-utils so the changed-package lint jobs pass again.

Move the test app helpers over to prepareSpecializedApp().finalize() so they stop depending on the deprecated createSpecializedApp entrypoint.

Deprecate all standalone mock API exports in favor of the `mockApis`
namespace. This includes the mock classes, their option types, and
the `ErrorWithContext` type. Inline option types into the `mockApis`
function signatures to avoid dependence on the deprecated types.

Remove @alpha tags from translation-related types and switch all
translation API imports in new frontend system packages to use stable
paths from @backstage/frontend-plugin-api instead of
@backstage/core-plugin-api/alpha.

Rather than removing the future prop, set v7_relativeSplatPath and
v7_startTransition to false so react-router stops logging deprecation
warnings.

Roll back the v7_relativeSplatPath and v7_startTransition future flags
and the Outlet-based route structure, keeping the version bump to
react-router-dom@^6.30.2.

Introduces comprehensive mock implementations for AlertApi and FeatureFlagsApi in @backstage/frontend-test-utils, following the 3-pattern approach (function, factory, mock) for consistency with existing test utilities.
The new mocks include useful testing methods:
- MockAlertApi: clearAlerts(), waitForAlert(), getAlerts()
- MockFeatureFlagsApi: getState(), setState(), clearState()
Also adds a mockApis namespace that provides these new mocks and re-exports existing mockApis from @backstage/test-utils for backwards compatibility.

Adds the snapshot() method to ExtensionTester, enabling snapshot
testing of extension tree structures. The snapshots use a tree-shaped
format that mirrors the extension hierarchy, with empty fields and
default values omitted for clarity.

Added support for API overrides in `createExtensionTester` and
`renderInTestApp` to allow tests to override specific APIs without
requiring wrapper components. This provides app-level API overrides
that are available throughout the entire extension tree.
The `apis` option follows the same typing pattern as `TestApiProvider`
from `@backstage/test-utils` for consistency and type safety.
Example usage:
```typescript
const tester = createExtensionTester(MyExtension, {
apis: [
[errorApiRef, mockErrorApi],
[analyticsApiRef, mockAnalyticsApi],
],
});
renderInTestApp(<MyComponent />, {
apis: [
[errorApiRef, mockErrorApi],
[analyticsApiRef, mockAnalyticsApi],
],
});
```
This enables cleaner tests with app-level API overrides, eliminating
the need to wrap components with TestApiProvider in many cases.
