Logger calls use f-strings instead of lazy % formatting

[KrishanYadav333]

Problem

Several logger calls across the PyASL codebase use f-strings for message formatting:

logger.info(f"Pipeline type: {ptype}")

This is an anti-pattern because the f-string is eagerly evaluated even when the log level is disabled, wasting CPU cycles unnecessarily on string construction.

Expected Behaviour

Logger calls should use lazy %-style formatting, which only evaluates if the message will actually be emitted:

logger.info("Pipeline type: %s", ptype)
