Language Persistence Issue in Enatega Multivendor Rider App

Describe the bug
Changing the language in the Enatega Multivendor Rider App is not persisting after closing and reopening the app. Despite successfully changing the language within the app, the previously selected language is displayed upon reopening, creating a discrepancy between the language setting and the actual app content.

To Reproduce
Steps to reproduce the behavior:

Open the Enatega Multivendor Rider App.
Navigate to the app settings.
Change the app language to a different one.
Close the app.
Reopen the app.
Expected behavior
The app should remember the selected language, and upon reopening, the displayed language should match the language set in the app settings.

Device: iOS only

Start by reproducing the language change and app restart flow on iOS, then trace how the app settings language is stored and restored. Verify the selected language survives closing and reopening the app, and confirm the displayed content matches the saved setting.
