4/post admin trees

[dbenshachar]

Developer: {David Benshachar}

Closes #{4}

Pull Request Summary

Adds authentication method for future POST requests by using function that creates a client using bearer tokens. Adds POST function with error handling to insert requests into tree table on supabase.

Modifications

Modified supabase-client.ts to add createAuthenticatedClient which creates a client using the bearer token. Modified api/admin/trees/route.ts to include POST method with documentation.

Testing Considerations

I have tested removing required parts of the body for insertions as well as including or removing optional parts of the body. I have verified that the error handling for these cases is correct. In addition, I have tested invalid and expired bearer tokens for authentication. This testing has verified that the request can insert parts into the "trees" table on supabase.
