Oleg Isonen bffc4597fe fix: Prevent outgoing page rerender during navigation (#5800)
**Description**

Prevents published pages from rerendering the outgoing generated page
during pending internal navigation.

React Router can rerender the current route while the next route loader
is pending. The generated `Page` was rendered directly inside that
route, so the entire outgoing page could rerender before the next page
appeared.

This adds a memoized `PageBoundary` keyed by `url`, so the generated
page only rerenders/remounts when the actual page URL changes. The SDK
context value is memoized by `resources`, preserving same-URL resource
updates without exposing the full page tree to unrelated
pending-navigation rerenders.

**Changes**
- Added `PageBoundary` to React Router and Remix/default HTML route
templates.
- Kept `key={url}` behavior for HTML Embed script reloads on dynamic
pages.
- Added regression tests for:
  - no outgoing page rerender while destination navigation is pending
  - same-URL resource changes still update generated page content
- Added Vitest setup for `sdk-components-react-router`.
