Smoother reactions and clearer feedback counts in the dashboard

We've made it easier and more pleasant to share your reactions and feedback on changelog entries. Previously, the system sometimes slowed you down when you were just adding feedback or your email, but now rate limiting only kicks in when you switch reaction types, letting you engage more naturally.

**See reactions right from your dashboard**
You can now spot how others have reacted directly in the dashboard changelog list, giving you a quick sense of which entries are getting the most attention without needing to open each one.

**Improved look and feel in light and dark modes**
Feedback components now adapt better to your theme preferences thanks to updated styles that work seamlessly whether you're using light or dark mode. This means reaction prompts are clearer and more visually consistent across your experience.
