DashboardController has missing @PreAuthorize condition regarding Rights and Role Matrix

[poojapatel23]

Description

Trace-X API handles three roles: 'User' and 'Supervisor' and 'Admin'. Most of APIS are protected/Authorization by some roles.
As per my understanding, DashboardController has handles by all three roles and should be defined @PreAuthorize condition for it.

Not possible to test. Looks good to me. PreAuthorize annotation is now added for the DashboardController.
Ready for review.
