Enabling PHP strict mode of development.

PHP language is getting better version by version. While we started our journey on PHP 4.x (which is a 20 year old legacy) we have completed support for PHP 8.x in 8.2.0 release.

We are now gearing up towards compliance for E_ALL (during development mode).

To make it easier for tracking the PHP error at request level we need custom logger which can capture error without affecting the Ajax Response and also provide request URL context.
