Description: When the app is initially launched in dark mode on iOS, it correctly appears in dark mode. However, when you navigate to a page, like the calendar, using the menu, the app switches to light mode, which is inconsistent with the expected behavior.

Steps to Reproduce:

Launch the app on an iOS device in dark mode.

Use the menu options to navigate to a specific page, e.g., the calendar.

Observe that the app switches from dark mode to light mode.

Expected Behavior: The app should remain in dark mode when navigating to pages via menu options, similar to how it behaves when using the homepage hyperlink.

This issue does not occur when using the hyperlink on the homepage.
