Checking if the term is added anywhere else

[padwhen]

Bugs:

• [x] False Positive Duplicate Detention
• [x] Once click 'Delete', suddenly all notifications appear
• [x] 3. For example, there are 2 terms that are the same. So both will have a notification about the duplication, however, if I delete one, the other term will still have the warning about the duplication
• [x] 4. Somehow options 'delete-other' is not working properly

Additional features:

• [x] Relocate to exact position if there is a duplication in this deck.
• [x] Allow users to choose option 'Don't compare to other decks' (?)
• [x] Should have like a notification at the top of the page, maybe warn the user if they click save while there are still duplications

The duplication warning persists even after deleting one of the duplicate terms because the application checks against the decks from useContext(DeckContext), which isn't consistently updated. This results in the warning still being shown since the context still reflects the old state.

To resolve this, I created a local copy of decks and made sure to check and update against this local variable. This way, the duplication status is accurately reflected based on the most recent changes.
