feat(usage): show reserve and deficit pace on Limits - #11095

What Changed

Usage → Limits uses the composer bar's pace value and tooltip. describeWindowPace builds that value. WindowPaceCopy is the tooltip block, and Limits segment details render it. The mark on both bars is PaceLine, a grey tick a little taller than the fill.

Web and mobile share the value and the tick. A window with no reset or no duration draws no tick. The tooltip text is the only pace copy.

Why

Limits should show the same even-spend line the composer already shows.

UI Changes

These captures use mock quotas on the T3 Chat dark theme.

Before

The bars show quota left and the reset countdown.

After

The grey tick marks how much of the window is left. The tooltip uses the composer sentences.
