feat(trial-user-limits): implement trial member limit checks in project and team controllers

- Added TRIAL_MEMBER_LIMIT constant to enforce a maximum number of trial users in project and team member controllers.
- Implemented logic to check current trial members against the limit during user addition, providing appropriate responses for exceeding limits.
- Updated relevant controllers to utilize the new trial member limit functionality, enhancing subscription management for trial users.
- Enhanced error messaging to guide users on upgrading their subscription for additional members.
