refactor(handlers): lower case error messages (#2289)
* refactor(handlers): lower case error messages

also refactor verifyAuth function to detect malicious activity both with session
cookie and authorization header.

* refacto(handlers): simplify error construction

* fix(handlers): check prefix in authorization header to determine auth method

* fix(handlers): determining the method should be done with headers instead of query arg

* refacto(handlers): rollback changes of verifyAuth

* don't lowercase log messages

* Apply suggestions from code review

Make sure logger errors are not lowercased.

* fix: uppercase logger errors and remove unused param

* Do not lowercase logger errors
* Remove unused param targetURL
* Rename url variable to not conflict with imported package
