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.

Replace the MessageBus-based pane-context slot with a focus-driven one.
Panes keep their status widget locally; the FocusTracker holds the
focused pane's widget (activeStatusWidget) and ClidePane conveys it to
the shared slot only while its contribution is focused, re-conveying on
change and clearing on blur. The status-bar item just renders
focus.activeStatusWidget, height-clamped and marquee-scrolled when it
overflows. Removes the publish/subscribe race the bus version had.
T-150.
