chore(test): reduce default pytest log level from DEBUG to WARNING

[Pouyanpi]

The DEBUG level was flooding test output with verbose nemoguardrails logs,making it difficult to read test results.

• Changed default pytest log level from DEBUG to WARNING to reduce noise in test output
• Verbose logging can still be enabled per-request using --log-level=DEBUG or --log-level=INFO
• Fixed test that checks INFO-level log messages to explicitly set caplog.set_level(logging.INFO)

Greptile Summary

Changed default pytest log level from DEBUG to WARNING to reduce verbose test output. This is a sensible change that will make test results more readable.

• The change correctly updates the log_level configuration in pytest.ini
• Users can still enable verbose logging with --log-level=DEBUG when needed
• Note: Some test files have hardcoded logging.basicConfig(level=logging.DEBUG) which may override this setting for those specific test modules

Confidence Score: 4/5

• This PR is safe to merge with minimal risk
• The change is simple, well-justified, and improves test output readability. Score is 4 rather than 5 because some test files have hardcoded DEBUG logging that may reduce the effectiveness of this change
• No files require special attention - this is a straightforward configuration change
