fix: Correct journal entry redirection

[JustinhSE]

Overview

Currently, after saving a new journal entry, the application redirects users to the home page (e.g., the entry creation page or dashboard). Instead, users should be redirected to the "Past Entries" page to review their saved entries immediately. This issue aims to correct the post-save redirect logic, improving user experience and workflow efficiency.

To-Do

• Review the current redirect logic after saving a journal entry
• Identify the correct route or URL for the "Past Entries" page
• Update the redirect in the controller or handler responsible for saving entries
• Test the new redirect behavior to ensure it works as expected
