Improve axis formatting and bump version to 8.7.0

Refactored axis title and tick font handling in annotate_peak.py for better consistency and appearance. Added uirevision to layout for stable UI updates. Removed unused colour_dict argument from main block. Updated setup.py to version 8.7.0 and adjusted download_url accordingly.
