ClideMarquee honours reduced motion (MediaQuery.disableAnimations) (T-284)

The status-bar footer marquee drove a raw Ticker whenever its content
overflowed, ignoring MediaQuery.disableAnimations — unlike the turn indicator
(T-273), which stops on the same flag. Two costs: reduced-motion users still
got the scrolling footer, and the perpetual ticker was the historical
pumpAndSettle-hang culprit (its tests cope by only ever pump()-ing).

Unify on the one mechanism: read disableAnimations in didChangeDependencies
(as running_indicator does) and gate the ticker on it via _syncTicker(). Under
reduced motion the marquee never starts the ticker (stops + resets if running)
and renders the child statically (clipped, no looped copy). Toggling the flag
at runtime starts/stops the scroll.

Tests: reduced-motion marquee does not scroll and pumpAndSettle completes (no
hang); flipping the flag off lets an overflowing marquee scroll again.

 ### Fixed
 
+- The status-bar footer marquee now **honours reduced motion**: when the OS
+  reduce-motion setting (`MediaQuery.disableAnimations`) is on, a long status
+  line no longer scrolls — it renders statically (clipped) — matching the turn
+  indicator, which already obeyed the flag. Unifies the two animations on one
+  mechanism and removes a `pumpAndSettle` hang the perpetual ticker caused.
