fix(themes): restyle the animated-theme indicator (#1035)

Replace the raw hazard-triangle icon with a small amber motion chip
(shared AnimatedThemeBadge): an Activity glyph on a tinted rounded
surface. In the Theme Store it stays inline after the name; on installed
theme cards it moves from bottom-right to top-centre, clear of the active
indicator (top-right) and the uninstall control (top-left). Tooltip and
aria-label are unchanged.
