[BUG]: `/profile` renders for admins role

[ayush00git]

/profile works for admins as well which was designed for non-admins role users only. A known bug that was caused due to using admin role for the auth context in handlers/auth.go

case "admin":
		var profile models.Admin
		result := h.DB.Where("email = ?", email).Take(&profile)
		if result.Error != nil {
			c.JSON(500, gin.H{"error": "failed to fetch user profile"})
			return
		}
		// hand-pick the fields so the password hash never leaves the server
		userProfile = gin.H{
			"id":          profile.ID,
			"email":       profile.Email,
			"position":    profile.Position,
			"is_verified": profile.IsVerified,
			"created_at":  profile.CreatedAt,
		}
