Animations, GIFs and the globe now move for every reader

decePub no longer looks at the system's "reduce motion" setting, so everything moves the same way whatever it says:
- a GIF video in a post plays by itself, muted and looping, instead of waiting for a tap; it now also starts on a page
  just opened, before the first tap, where the browser used to hold it still;
- animated custom emoji move in the emoji picker instead of showing a still picture;
- the globe turns by itself while no located post is in view, flies to the posts, and its pulses, arcs and Sun move;
- going back to the top of a feed scrolls smoothly;
- tooltips, dropdowns, menus, folding sections, toasts, loading spinners, placeholders, progress bars, radio buttons
  and ratings keep their animations: the build now takes daisyUI's reduce-motion rules out of the stylesheet
  (tools/css/motion.py, run after every Tailwind build, in watch mode too).
