Chore: Enable `no-unreduced-motion` and fix errors (#86572)

* enable `no-unreduced-motion` in betterer

* move all animation calls inside handleReducedMotion

* fix violations + enable rule

* update rule README

* remove unnecessary transition from <Collapse>

* remove handleReducedMotion utility and add handleMotion to theme

* update to use new theme value

* handle Dropdown and IconButton

* handle AppChromeMenu and update lint message

* keep rotation at a reduced speed

* handle DashboardLoading

 To account for users with motion sensitivities, these should always be wrapped in a [`prefers-reduced-motion`](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion) media query.
 
-`@grafana/ui` exposes a `handledReducedMotion` utility function that can be used to handle this.
+There is a `handleMotion` utility function exposed on the theme that can help with this.
+
+#### Examples
+
+```tsx
+// Bad ❌
+const getStyles = (theme: GrafanaTheme2) => ({
+  loading: css({
+    animationName: rotate,
+    animationDuration: '2s',
+    animationIterationCount: 'infinite',
+  }),
+});
+
+// Good ✅
+const getStyles = (theme: GrafanaTheme2) => ({
+  loading: css({
+    [theme.transitions.handleMotion('no-preference')]: {
+      animationName: rotate,
+      animationDuration: '2s',
+      animationIterationCount: 'infinite',
+    },
+    [theme.transitions.handleMotion('reduce')]: {
+      animationName: pulse,
+      animationDuration: '2s',
+      animationIterationCount: 'infinite',
+    },
+  }),
+});
+
+// Good ✅
+const getStyles = (theme: GrafanaTheme2) => ({
+  loading: css({
+    '@media (prefers-reduced-motion: no-preference)': {
+      animationName: rotate,
+      animationDuration: '2s',
+      animationIterationCount: 'infinite',
+    },
+    '@media (prefers-reduced-motion: reduce)': {
+      animationName: pulse,
+      animationDuration: '2s',
+      animationIterationCount: 'infinite',
+    },
+  }),
+});
+```
+
+Note we've switched the potentially sensitive rotating animation to a less intense pulse animation when `prefers-reduced-motion` is set.
+
+Animations that involve only non-moving properties, like opacity, color, and blurs, are unlikely to be problematic. In those cases, you still need to wrap the animation in a `prefers-reduced-motion` media query, but you can use the same animation for both cases:
+
+```tsx
+// Bad ❌
+const getStyles = (theme: GrafanaTheme2) => ({
+  card: css({
+    transition: theme.transitions.create(['background-color'], {
+      duration: theme.transitions.duration.short,
+    }),
+  }),
+});
+
+// Good ✅

+  card: css({
+    [theme.transitions.handleMotion('no-preference', 'reduce')]: {
+      transition: theme.transitions.create(['background-color'], {
+        duration: theme.transitions.duration.short,
+      }),
+    },
+  }),
+});
+
+// Good ✅
