Add Support for Tags/Labels

[Ehab-d]

Is your feature request related to a problem? Please describe.
It's difficult to organize and find notes efficiently without a way to categorize them.

Describe the solution you'd like
Implement a topics feature to allow users to categorize and search notes easily.

Describe alternatives you've considered
Currently, I rely on manual searching, but it's time-consuming and less effective.

Additional context
Tags or topics or areas or labels whatever would enhance organization, making the app more user-friendly for managing large numbers of notes. I prefer Labels!
