Reduce log level within loops

[jo-elimu]

          **Optimize logging within loops.**

Logging within loops can be expensive. Consider reducing the log level or aggregating logs.

- logger.info("word.getText(): " + word.getText());
+ logger.debug("word.getText(): " + word.getText());

Thoroughly test & benchmark the code to ensure it meets the requirements. `````suggestion List words = wordDao.readAll(); logger.info("words.size(): " + words.size()); for (Word word : words) { logger.debug("word.getText(): " + word.getText()); for (LetterSound letterSound : word.getLetterSounds()) { letterSoundFrequencyMap.put(letterSound.getId(), letterSoundFrequencyMap.getOrDefault(letterSound.getId(), 0) + word.getUsageCount()); } } `````

The webapp in production is configured to only output logs with threshold level INFO or higher: https://github.com/elimu-ai/webapp/blob/main/src/main/resources/log4j2_PROD.xml#L3
