Remove unused ConfigException class, make code style adjustments

Deleted ConfigException class as it was not being used anywhere in the project.
Code style adjustments were made to conform with the PSR-12 coding standard. This includes property and variable naming conventions, use of strict equality operators, reformatting of code and removal of unnecessary comments. The .idea/php.xml file was also updated to a newer version of the library.
Log functions are updated to throw exceptions for non-existent message and invalid level. Also, LogLib is now registered/unregistered  as an exception handler.
Other adjustments were made to achieve consistency in the codebase including renaming properties for clarity, moving magic strings into constants, improving code readability and adding descriptive comments.
