Fix after_save webhook callback handling

[AdrianCurtin]

Ensure after_save webhook handlers that return a Parse::Object no longer suppress model callbacks. The change makes callback dispatch depend only on request origin (trusted Ruby-initiated saves still skip webhook callbacks; client-initiated saves always run them) and documents that the handler result is normalized to true so returned objects cannot leak into responses or logs. Bumps stack version to 5.4.1, adds a regression test for object-returning handlers, and updates the changelog.

Pull request overview

This PR fixes after_save webhook callback dispatch so that model callbacks (after_create/after_save) are no longer suppressed when an afterSave handler mistakenly returns a Parse::Object. Callback dispatch now depends only on request origin (trusted Ruby-initiated saves still suppress webhook-side callbacks to avoid double-runs; client-initiated saves always run them), and afterSave handler results are normalized to true to prevent object leakage into webhook responses/logs.

Changes:

• Update Parse::Webhooks.call_route to run after_save model callbacks based solely on request origin, not the handler return value.
• Add a regression test covering object-returning after_save handlers and verifying the result is normalized to true.
• Bump version to 5.4.1 and document the fix in the changelog.
