Review changes.

* Improved exception handling logic to use the base CicsException.
* Renamed the CJLL transaction to WLPH to avoid the CICS reservered prefix.
* Clean code:
  - Use constants to avoid magic strings.
  - Improve logic flows and avoid repeated calls.
  - General code quality improvements.
* Updated links in the README.
* Fixed names in WLPH transaction definition.
* Added instructions for running the WLPH transaction.
