G8: a notice leaves quicker than it arrives

The notice chip's motion was mostly there (a drop easing out on the
Motion flavour, a dissolve easing in, Lift's shadow in tier 4 at its
fade). Its dissolve took 300 ms against a 180 ms fall, the wrong way
round for §8.1 (leaving quicker than arriving, 100 to 160 ms):
MessageDissolve now defaults to 150. The field comments had the two
easings swapped; the stack test pins a longer dissolve for the case it
checks. docs/config.md and docs/effects.md say so.

Tests: both timings in their bands, leaving quicker. Gates as G7 (no
golden moved). Feel review: .scratch/render/notices/.
