Add token to requests sent to SCEvents' protected routes

[steeevin88]

resolves #2086

CHANGES

• SCEvents endpoints need to be protected --> we need a way for SCEvents to know that if it gets a request, it's actually from Clark
• to do this... we'll pass the JWT token to protected requests... and determine if the user is valid (ex. is an admin, is a member)

TESTING

• created event

• backend logs showed it worked
