Update dependency ruff to v0.15.14

Add a Drink.category field (beer, alc_free_beer, radler, alc_free_radler,
soft, water) and apply per-category gradient backgrounds to the booking
buttons so users can recognize drinks at a glance. Sort buttons by
category, shrink them to a 3:2 aspect ratio, and switch labels to more
verbose brand names (Sternburg Export, Ur-Krostitzer, etc.).
