Enhance project member drawer localization and UI

- Added new localization strings for "members" and "copy project link" in multiple languages (Albanian, German, English, Spanish, Portuguese, Chinese).
- Updated the project member invite drawer to use a modal instead of a drawer for improved user experience.
- Included a button in the modal footer for copying the project link, enhancing functionality for users.
