Dashboard Improvements

[RevanchistX]

Fix infinite redirect. Issue appears when db is down, and fetching reservations fails, leading to a redirect to login, which is then authenticated and redirects back to dashboard

Remove extensive logging when opening /dashboard/ page

New functionality:
Dashboard navigation - include links next to logout button to the following pages:

• /dashboard/blogs
• /dashboard/employees/
• /dashboard

Dashboard table - add column for employee.
The employee should be able to apply assign to self to take the reservation.
admin can use a dropdown to select employee instead.
