fix: update patch targets for create_post and create_text_post in tests

The tests were failing with an AttributeError because they were trying to patch
functions directly on the main module (main.create_post and main.create_text_post).
These functions actually reside as attributes of the app object (main.app.create_post
and main.app.create_text_post). This commit updates the patch targets accordingly.
