Enhance project member invitation feature with new localization and UI updates

- Added new localization strings for "invite member" and "also invite to project" across multiple languages (Albanian, German, English, Spanish, Portuguese, Chinese).
- Updated the project member invite drawer to conditionally display UI elements based on the context of the invitation (from assigner or not).
- Introduced a new state management feature to track if the invitation is initiated from the assignee selector, improving user experience.
