Is your feature request related to a problem? Please describe.
Currently, the app doesn't automatically match the device's theme (light or dark) when first opened. This can create a mismatch between the device settings and the app’s appearance, which might confuse users until they manually change the theme.
Describe the solution you'd like
The app should detect and apply the device's default theme (light/dark) when first launched, as long as the user hasn't already selected a theme in the app. Once the user chooses a theme, their preference should override the system setting and be saved for future use.
