Don't include '.0' on minutes and hours for durations when passed as large floats.

Description

I was seeing duration values like Time: 178.236s (2.0 minutes 58 seconds). This change just removes the ".0" off of the "2.0 minutes" by casting hours and minutes to ints.

Checklist

Some additional notes on development: Since I have pgcli installed with pipx, running the tests with just pytest seemed to be picking up THAT version of the code instead of the code that I was altering. Running uv run pytest test_main.py fixed that, consider updating the CONTRIBUTING document accordingly. Similarly, for the pre-commit hook to work, I ran:

$ uv pip install pre-commit

I would also recommend some details about pre-commit and how that can work with uv in the CONTRIBUTING document.
