Chore: Mark dead Route::matchedPath methods and unused Http::$requestContainer as @deprecated

Route::setMatchedPath() / Route::getMatchedPath() are no longer called by
the framework after Router::match() switched to returning the matched
path in its return tuple. Http::$requestContainer was never assigned —
per-request state lives on the adapter's container.

Left in place for backwards compatibility; flagged for removal in a
future major release.
