• Added getAllTimeprojectMembership endpoint (GET /api/project/:projectId/alltimeusers/) that queries users by projectHistory instead of projects
• Updated putUserProfile in userProfileController.js to update projectHistory whenever a user's projects change
• Added getProjectHistory and postClearProjectHistory utility functions
• Added new routes in projectRouter.js and userProfileRouter.js
• Fixed getprojectMembership to use mongoose.Types.ObjectId for proper ObjectId matching
