Frontend dashboard.jsx changes

[harimurugan1989]

Upon successful login, it will redirect to dashboard page if there are multiple roles. We need to check the role of the user logged in (in our case diabeticsAdmin, HospitalAdmin, doctor and patient) and redirect to their corresponding dashboard pages.

Url for these pages will be:

diabetics admin --> /dm/diabeticsadmin
doctor dashboard --> /dm/d/userobjectId
patient dashboard --> /dm/p/userobjectId
