fix: address QA failures in PR #134 — AJAX nesting, hook typo, test coverage

- Fix: Nested AJAX handler method (on_ajax_sync_runware_models_now) moved to proper class scope in class-ajax-handlers.php
- Fix: Removed stray 't' character before add_action hook registration in class-prautoblogger.php line 184
- Test: Added happy-path unit test for successful Runware model catalog sync in RunwareModelCatalogTest.php
- All files pass PHP lint validation
