Fix path traversal vulnerability in ViewComponentsSystemTestController where sibling directories sharing a string prefix with the allowed temp directory could bypass the path containment check. The start_with? check has been replaced with a separator-aware prefix check, and nefarious path errors now return a 404 instead of an unhandled exception.

Fix preview route vulnerability where inherited methods on ViewComponent::Preview (such as render_with_template) could be invoked via the preview URL, allowing arbitrary internal Rails templates to be rendered with attacker-controlled locals and request parameters. render_args now raises AbstractController::ActionNotFound for any example not explicitly declared on the preview subclass.
